I'm about to go pick up some Rustoleum lense tint and clear coat to tint and clear the gross, oxidized reverse bar on my '05, and probably clear coat the third brake light while I'm filling the spoiler with expanding foam. I've got a few questions though if anybody has some advice for me, as this is my first time doing any painting on a car past touch-ups.
I'm assuming I should sand the reverse bar and brake light before doing any painting to remove oxidation and other crap, but when else should I sand the lights? I believe I've mostly seen people sand after all the tint is laid down, and after every clear coat. Should I sand the last coat as well? I've got a polishing attachment and some polishing compound for a dremel so I'll polish them up afterwards, I'm aiming for a factory level of gloss.
Any suggestions on sandpaper grit? I'm going to pick up some 1000, but maybe I should wetsand at the end?
And how many layers of tint would you personally go on the reverse bar? My rear windows are tinted at 20% so I don't want to cut out too much light, but I'm not leaving the little reflectors exposed because it looks a bit silly. I do have bright LED reverse lights ATM from Diode Dynamics, similar to the Cree's with a high power LED facing forward and four on the sides.
I plan on taking my time with this so not urgent by any means, I've just seen a lot of variance with how people do their work. If only Flip still painted :/
