Can you PM me or post a little better write up, please? I am wanting to do this to my grille and its the aluminum silver one from shelby.
Unfortunately, I didn't take any pics during the process because my fiancee' has our camera. I will give you a run down of what I did, feel free to PM me any specific questions.
Paint used: Valspar primer, Valspar black for metal
Sandpaper: 220 and 320 grit
1. I removed the grill from the car and removed it from the housing. I forgot to buy painter's tape so I did it the longer way.
2. I started wet sanding the grill with the 220. I started going with the groove of the grill (laterally) then switched to going in circular motions. I honestly cannot remember how long I sanded for, but it was at least 20-30 minutes. I then switched to the 320 grit and went back to laterally sanding it.
3. After I felt I had smoothed it as best as possible, I put down a lite coat of primer.
4. I let that dry then repeated step 3 twice to make sure I got a good base.
5. After my last coat of primer I let it dry then started sanding (not wet sanding) with the 320 grit. I felt that was the best way to smooth the grill out and create a good surface for the paint to stick to. I sanded for about 30 minutes then began the painting.
6. Each coat I painted one the grill, I painted as if it were going to be the last. I would put down a coat of black then repeat step 5. I did that about 5 or 6 times until I felt satisfied with the way it felt after it dried. I could tell a difference in the texture of the grill after each sand and coat.
7. Re-install
I will also recommend putting a coat of clear on it to help stop it from chipping. I will be doing that sometime this week if I have time.
