How to Paint Chrome Tube Bumpers?
So I've got these tube bumpers on the front and rear of my car that I can't stand and are starting to rust. I need to know how I can go about painting them flat black and have 'em last for a good year or two.
There's a pic of 'em.
I was thinking this process, but I've also started reading into needing muariatic acid to break down the chrome, and if that's true, then these will have to stay.
1. 120 grit sandpaper
2. clean off with acetone, twice,
3. 1st layer primer
4. 400 grit
5. 2nd layer primer
6. wetsand 800 gritt
7. 1st layer Rustoleum flat black
8. 1200 grit
9. 2nd layer
10. 1200 grit
11. 3rd layer
12. 1200 grit
13. clear coat (2 layers)
14. 1600 grit, 1800 grit, then 2000 grit
Then buff it out from there.
the reason for so many layers is that I plan on spraying really lighty rather then going heavy.
Let me know if I'm doing something wrong, some suggestions, etc. The bumper will be taken off and hung in my basement which will have blankets and everything laid so it's not dusty.
Sounds to me like you have the right idea. Good luck with the project.
geez that's a lot of work... Here this might be easier... remove chrome bumpers... give to trash guys, go to parts yard remove stock black TJ bumpers install. If that does not work for ya....
Remove the rust.. go over with some rust to primer product, then cleaner and paint... repeat as needed.
Alright, unfortunately, I don't have the time now to go get all the materials so this will have to wait until next weekend :( Ended up just her the old foil + vinegar to get some of the lighter rust and I have to say, it looks a whole lot better. Still hate chrome on any car, but this is almost tolerable.
If you're gonna paint em anyway, go to Walmart and pick up some SOS pads...it may scuff em up a lil bit, but I used to use em on chrome BMX bikes I'd get that were covered in rust...it'll get about 90% of the rust off as long as it's not too deep. Used em on my chrome rims for my old truck as well. I didn't have any problems with it scuffing up the chrome btw...but when using a steel wool product designed for heavy cleaning, it's something that needs to be kept in mind IMO.
