In this How To you will learn to paint aluminum/chrome on your bumpers etc. I will be using my aluminum bondo board to show because I don't have a piece that I want to paint.
120-180 grit sandpaper
Body filler (bondo, if you have dents you want to smooth out)
Beer (optional, but does help!)
First you take your shiny "project" and it should look like this
Next you want to sand it with 120-180 grit sandpaper as primer/paint won't stick to shiny surfaces. And it should look like this
Next wipe off all the dust and crap and fix any imperfections you don't want to be seen, aka dents, dings, deep scratches etc with bondo, sand smooth. Repeat process until satisfied.
Then if you want you can spray some adhesion promoter or something of the like but its not neccessary.
Next spray a coat of High Build primer onto your project let dry fully, then sand smooth, then add another coat and let dry, then sand smooth again. if your using thin cheap primer like me add a coat, let dry, add another coat let dry, add a 3rd coat and let dry.. here's what it looks like in the "stages"
1st coat of thin primer
2nd coat of primer
3rd coat of primer
Now sand it down a little bit and make sure there's unwanted imperfections still, if there are fix them, if not continue to the next step
Next after sanding final coat of primer, paint the project.
And that's it. Oh and don't forget your giant pair of sissors to cut your sandpaper to size!
optional is beer.... I had a Sleeman Honey Brown while doing this. Good Luck.. It's pretty easy.
