While on this topic, does anyone know of a place in the Denver CO area that can paint a Carbon Bike? Hottubes would be my first choice, but i'd like to avoid shipping it off if possible.

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.

Um, OK. Seam's like your a pro now!!! Good for you.
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.
