I know this is an old thread, but up until very recently I worked for a sign company and we did a lot of vinyl wraps for vehicles. A friend asked me if I could wrap a TT helmet. That was last year.. It looked awesome and complimented the kit rather well. Was asked again to do it again for the 2019 kit. Just finished that helmet but as the design will remain a surprise for a few more weeks, Thought I would post the 2018 version: It complimented the kit well. I did the decals for the draft box and also changed the wheel graphics to match the graphics.
I used 3M IJ180C with 3M Gloss overlaminate to wrap the helmet. This is another popular wrap film. The graphics were made in 3 parts. For 2019 I managed to do it with 2.Same Rudy Project Wingspan helmet. I do not recommend this to anyone. The vinyl will destroy the original decals on the helmet if you attempt to remove it. I also recommend removing the decals completely prior to application as they most likely start to tear off at some point in the installation process and will form wrinkles or will cause lift-off in the process. This is NOT EASY to do. It's also cost-prohibitive. It's also probably against some obscure USAT rule though so far no officials have said anything other than "wow that's cool". It ADDS weight and is slightly less aero.
But it looks really cool.Sometimes that's worth being .0002 seconds slower.
