As we all know, prep is EVERYTHING. Bad prep = bad paint job, no matter what. Good prep + Meh paint = Better than above.
I 1st decided to paint the shield covering the light. If you look behind it, it is actually flat black! So I did the ENTIRE flat black.
Prep, using 800 grit sand paper I did, a little course, but worked good.
Next, the ribs on the side. I went to the junkyard and trashed apart a headlight. Tearing the lens off (old adhesive is even strong) and cracking it, I found that the ribs are still 1 layer of plastic.
So what gives them their color? NO YOU DONT HAVE TO PAINT OVER THE LENS!!!
Its as simple as this...flip it over, and look. I gouged at it with a scredriver, and found out it was merely paint on the back.
So far, the best way I've found to remove the paint is laquor thinner. I still was having a hard time so the body shop near my is working on them. I'll edit this once I find works. But I hear theres DOT 3 Brake Fluid, oven degreaser, etc.
So Next, the housing. So, sand down what you need based on your project. I used too low of a grit 1st time, so I had a mistake needing to fix, so I suggest a scotch brite pad or whatever, or 1000+ grit. You just need to give it a good fade, and something to grip to.
Now, tape off all that you need safe, which in my case is the entire inside housing. Also remember to shove a little gunk tape in the breather hole, or else you'll have paint enter/exit.
As known already, use many light coats, not 1 big globby coat. At 1st I never understood that, but its simple as... The light will still build up, but it dries faster, making a stronger hold for the next layer. And in time, though it doesn't look like its even (some places dry faster than others, some places are somewhat translucent), it will be. A big dark wet paint job will look good to start off with, but it will run, dry longer, tough to touch, wont adhere nearly as well....etc
Once complete, you will have a sexy housing. Chrome edge and inside, a nice textured black outside, and perfect for the retrofit.
Time to start mounting the retrofit
