I dipped mine the second day I had the car. I used just plain black and it has held up for almost 3 years. I will be peeling it off to do a different color soon though. Just make sure you spray enough coats (1 can per wheel is recommended).
The dupicolor spray sucks! I got the gloss black to do my mirror caps and even after 6 coats they were "spiderwebbing". I'll stick with PD, easier to spray and peel.
Dont do it, I got the hard covers for my 16 and they cracked one of my lenses. So now I have to replace the whole assembly. Just get them tinted and be done with it.
Not sure about them, I would use this company for a steering wheel though

Hardest part was taking off the bumper but still easy enough. I'll get some pics/videos for you.
I have access to a lathe or water jet or what ever... lol even a laser engraver if needed. Thinking of doing the Imperial Symbol for mine (not that new First Order crap)
I really hope one of these days we get rid of the "Back Pressure" thing. You dont want back pressure...

easy enough to take a dremel to the blocked off area and open it up. Im still looking for one that can switch between red and white. The white one for daily driving but then switch to red for car shows.
