Painting a bumper
The before:
Removed bumper (4 bolts) and removed moulding (plastic pinch clips on the back side), washed it down front and back. Using a 60 grit sanding pad with my angle grinder I sanded the entire bumper to remove the rust and any flaking or loose bits of chrome. I'll point out that a 60 grit on an 11k rpm grinder will eat metal away pretty quick, so don't sit on a spot too long or you'll make divets. It is imperative you do the full exterior bumper surface to make certain no chrome chips flake off later. Pay particular attention to the edges of the flaked or peeled chrome so that you don't have lines. After the 60 grit, I changed to a 120 grit and went over the surface again to feather it and give it a consistent looking surface. I then primered and wet sanded twice at about 30 minutes apart using a self etching primer that was wet sandable. I let it cure overnight and started again in the morning after 14 hours of curing time. I used rustoleum high performance enamel in a semi gloss, and gave it 3 coats with wet sanding in between the coats spaced at 1 hour. Let that cure overnight as well (I let mine go 24 hours before handling it). Reattached the moulding and the bumper in the morning, the surface is silky smooth, and the truck is starting to look like the pimp-mobile that it is.
Afters:
Total cost: 20 bucks in paint, 10 bucks in sanding pads, 15 bucks in Shiner Boch.
Thanks for reading, lemme know if you have any q's.
