good morning, I will be getting my bumpers back from the local platers this week, in the past I noticed the backside of fresh bumpers get surface rust pretty quick... I was thinking about spraying them with epoxy primer and some kind of quality paint... so heres my question, how would you guys prep the metal and what kind/brand and color of paint would you use.. im assuming a color that would be a natural steel tone. Any suggestions are welcome and appreciated.. thanks Rich
 
After the chroming about 30 years ago, I sprayed mine with that rubberized rocker paint stuff. Last winter I removed the bumpers for the car repaint and they still looked 100%.
 
OSdart...ive never had much luck putting clear on bare metal, it seems to yellow and flake off.. id like to use epoxy as a good base and then some sort of paint.. maybe an Eastwood product that simulates bare steel, just wondering what others have done.. thanks again guys
 
guys, Rustoleum is a decent product but wouldnt an epoxy primer followed by Rustoleum be a better choice.... these bumpers are freshly chromed and there is no rust on the inside .... im thinking long term, i dont really like applying any paint without a quality primer first, that includes clear coat over bare metal
 
My bumpers were new too when I coated the backside with Rustoleum silver spray paint. That was 15 years ago and there isn't rust on my bumpers to this day. I'm not sure there would be any rust if I had not painted them.
 
I'd paint them with some sort of under coating, clear will just flake off if not prepped.
 
scuff them with some 100 grit then apply a roll on rino liner. that stuff is wicked
 
From a painters perspective, on steel paint needs a mechanical bite, that means a rough sanding with 80-120 grit. Me personally I wouldn't sand a new bumper, you risk breaking thru and entering a chance for rust. Use a good quality undercoating and coat it good. If you get one that is paintable you could top it with some silver. I think the black would look better. Undercoating is the best solution for a long term stick.
