The material that the frame is made out of will be a big factor. You might want to provide that info.

I'm looking at doing the same for a 2011 Dogma. Any suggestions on where to start? My search has come up short so far.

Unless your existing paint is failing I would not strip it. Sand with 600 grit wet paper and scuff pads and go from there.

There is a product out there called Carbolift, that is supposed to be perfect for this purpose - a stripper made for carbon fiber. I have tried contacting the company a couple of times to buy some, but they have not returned my e-mails or phone calls, so I'm not sure if they even exist anymore. TriRig.com did a review of it, and it seemed pretty effective.

I did find a couple of places that sell it:
http://store.trainingfx.com/Carbo-Lift-500ml (the prices are Canadian Dollars, by default)
http://www.aircraftspruce.com/...g/cspages/carbol.php

As a disclaimer, I can't say that I have any experience with it, so I have no idea how much you need for a frame, if these guys actually have it in stock, how well it works, etc. If you do get some, I'd love to hear how it all worked out for you.

I've been a automotive painter for over 25 years. Do NOT strip the original finish off a carbon frame!!! This will destroy your frame especially if you use a chemical stripper.

Best way to refinish a carbon frame is to lightly sand the original finish and that's it. If you've never done this before leave it to a professional, you will be saving yourself time and money.

I have worked in the composite industry for 10 years. Please don't use paint stripper or any other type of chemical to remove the paint, it will attack the resin system and basically destroy your frame. Best is to use fine sandpaper.

This is definitely not a DIY project. Any recommendations on professionals to turn to for painting a carbon frame?

Not a DIY project. Your likely to do more damage than anything else and will cost you a lot more in the long run to repair your mistakes.

Painting a carbon bike frame is no different than spraying a automotive part so find yourself a body shop that will sand and spray it for you.

That Carbolift sounds a bit sketchy, product description:

"Use to safely remove finishes from fragile work pieces and hard to reach areas. Carbo-Lift is:

  • An opaque gel, tenacious, does not off gas, can survive being shot (don't ask), actions can be halted immediately by use of water - just like a good employee
  • Sensitive to temperature and prefers warm weather 24 degrees C + (although it will work down to 2 degrees C, if you have all the time in the world!).
  • Manufactured from the tears of our chemists in a special process which asks clear coat, paint and primer alike to sod off - in a gentle Canadian way which does not negatively effect the underlying substrate.


What it Does and Doesn't Do

  • Does not cook you breakfast, does allow you to go and enjoy breakfast while it works for you.
  • Don't eat, although so non-toxic it can be safely wiped off with your hands, who knows where your product and its paint has been!
  • Do keep it warm while it works, (remember Oompa Loompa's like the heat) optimum temperature is 24 degrees C to 35 degrees C.
  • Do wash Carbo-Lift off with water when you are happy with the amount of finish removed.

Yeah, the attempt at humor doesn't really do much to make you feel good about the product, does it?

To the OP - you're getting a lot better advice from other folks with real experience, so please disregard my post. I apologize for offering some bad (or at least questionable) advice.

Do not use any sort of chemical or paint thinner. It will destroy your frame. To remove paint and decals from a carbon frame, you have to hand sand the entire frame. We wet sand. It certainly takes some time.

We reached out to Carbo-lift given the nature of our business about their product, but never heard anything back.

Check out the weightweenies forum. There's lots of threads documenting people's frame stripping projects using various methods (sanding, Carbolift, razor blades). From what I've seen, it's a TON of work. Maybe it would be a better project for the off-season.

Also, stripping the frame can reveal all kinds of imperfections (bump, dips, pinholes, irregularities in the CF weave) that are hidden under paint or filler. This would not a big deal if you plan on repainting the whole frame a solid colour.

I did a DIY project on my Specialized transition this winter. I ordered Carbolift and found out it does not work all that well even when following the instructions to a 'T'. I ended up using 600grit sandpaper and was overly cautious taking it down to the bare carbon. Took a while with the sandpaper, but didn't have any issues. Once i got it to the carbon i lightly sanded with 1200 smooth it out. I was very happy with the results even though I found out I am not the best at taping! I posted some pictures of it in the specialized thread.

Yes Kevin, some folks just don't get it! The other thing is that prepping & painting frames is not a money maker for us.

The other thing is that every time I gave a quote for labour and material I always got a puzzled look and "Why so expensive?". So for that reason I don't even bother giving quotes anymore, just not worth the hassle.

I disagree that this is not a DIY project - I did it myself with no prior spray painting experience:

Paint job is still going strong.

I posted the process in this post:
http://forum.slowtwitch.com/...nickag%20p2;#3465120

Basically, did not chemically remove the original paint, I sanded/scuffed the clearcoat to give the new paint something to adhere to.

Not to be a dick or anything, but remember that the pro you take your carbon frame to, was an amateur once, and there was the first time he (or she) worked on removing paint from carbon.

I'm not claiming to be a pro. I am however highlighting that there is no voodoo magic in scuffing the original paint to prep it for painting. You said yourself that you won't do it because it's a pain in the ass. I agree with you on that, prepping a carbon frame for painting is a labourious manual process, that should not be undertaken by chemical means.

I am pointing out that carbon can be painted, it will not simply fall apart by scuffing the clear coat.

There really isn't in taping or spraying either. A pro can do it 10x faster and with a lower likelihood of mistakes, but in this age where everything is done for us, you can take pride in being a solid amateur craftsman.

We have refinished many framesets, and as a few other people have said, it's extremely time and labor intensive. It's not a fun job, and not many people are willing to pay the money to do the job right. Sanding a frame and fork properly takes several tedious hours. Painting it is actually the easy part. Basically, we tell customers that we're not willing to strip a frame all the way down to the bare carbon because it simply takes too long. Besides, there's a reason why many carbon frames are painted - the paint is hiding a lot of imperfections in the carbon.

Carbolift works okay, but we've been less than impressed with their customer service, so we just stick to hand sanding. We start with 180 grit to flatten out any raised logos/decals, then we step up to 320 grit before painting. We will re-finish a painted frame with another paint scheme, but we will not completely strip a painted frame. We can take a nude finish frame with decals/logos and sand them off so the entire frame is nude finish. That's about it.

I'd love to hear the magical "pro" process that makes this such an inconceivable DIY project. Does it involve something other than spending a large number of hours carefully wet sanding with 320 or 600 grit sand paper until the surface is smooth and free of defects? I will grant that the process is: tedious, time consuming, patience testing, slightly messy. One thing it is not: difficult. If you have the intelligence to not use 100 grit paper or a DA sander and don't try to remove all the paint (and thus almost certainly dig into the frame itself), it's pretty simple.

you can always tell the diference between a DIY or a pro paint job. If you want a simple one color paint that you could do it yourself but if you are looking for something more complicated and nicer, in my opinion, you should get it done by a pro.

As a painter who specializes in bike frames I do not use any chemical strippers on carbon. My Process on a new carbon frame would be to remove the factory paint down to the primer. This is done with sandpaper. Once acceptable the frame is primed and repainted.

I have stripped down to bare carbon many times at the customer request but it is not needed unless you want bare carbon or the factory primer is bad. I also charge extra to go to bare carbon.

Being a good painter requires practice and knowledge of the materials. I will answer any question but cannot give you the practice.

I painted a carbon fork recently, I got the paint from a good automotive paint store.

I used enamel that they recommended, they mixed it and put it in spray cans for me.

They told me to use a scotch bright pad and clean up the existing paint really well since it was good paint already. I did as they said, sprayed it with light coats and it came out really well.

I wouldn't say it is the reason, but knowing that a part will simply be painted over later takes a lot of the pressure off to get the cosmetics perfect. I've been doing a good bit of DIY with some carbon fiber that has a pretty crazy weave, and it has been taking forever because the fact that I bought the fabric to show off the weave means that I have to be careful to get it perfect...

(The pattern looks cool as hell, but the tradeoff on the cool pattern is a looser weave that doesn't hold together as well)

Been wanting to do some custom paint on my giant trinity too..... love the bike but hate the one blue thing on the frame, which is the giant logo on the side. I really want it to be a different color. So..... i was thinking of just tapeing off around the logo & brushing on automotive paint over it.... any opinions on this? Will it work? I just really dont wanna get the whole frame sanded & repainted, when all i wanna change is the color of just the one logo.

Time to resurrect this thread. Does anyone have any experience bead blasting a carbon frame? I've read a few blogs from folks that have had success doing it. Sanding would take way too much time and patience.

Not sure of bead blasting but soda blasting is the way to go if the user has a high end commercial soda system.
I have used a cheap model and it does work very well but takes long for a frame and u waste lots of soda which costs $$

What is the severity of damage? Is the frame clear coated in gloss or is it flat?

I sanded down the bad spots on a Felt AR5 frame I bought used. It had chips and some minor peeling clear coat. I have painted cars before and have a decent HVLP spray gun. I was able to clear coat my frame and it looks pro. I would say that 99% of the people on this forum shouldn't do the same. If you have no previous paint experience except that time you spray painted your BBQ with a rattle can and it "looked legit" you should re think undertaking such a project. If you are comfortable with sanding, wet sanding, spraying clear coat, and have all the materials at your disposal go for it. But odds are if that were the case you wouldn't be here asking how to do it.

You could do what a lot of hot rod guys do and paint it with John Deere Blitz Black. You would have to sand down the frame entirely and ensure ALL grease is gone and the frame is properly prepped. It would probably come out bad ass if you got some black gloss graphics to go over it. That paint does come in rattle cans as well as quarts and gallons for spray guns. My .02

Just realized this was an old thread with a new topic sort of...

my advice would be not to bead or soda blast carbon. Having used both it seems like a bad idea.

I'm keen to get my carbon road bike painted, but prices seem high - AUS $800. Would automotive sprayshops be willing to do bikes? I'd imagine most of them would simply say no, because it's not something they've done before, but is it the same principle. Plan B would be to do it myself, which I'm not too keen unless it really is quite easy. I was going for a matt black finish.
