Metal coating.

Merci Monsieur!
First, I'm going to do a meticulous prep job.
Then, I'm going low tech with the Rust-Oleum self etching primer and black semi-gloss just like I use on my sliders. Many coats.
This way, it should be easy to touch up, even 10 years from now.
Powder coat is not as easy to touch up in my experience.
As an alternative, I like to use the following coating:
1-Sand blast part once finished.
2-Use zinc chromate primer immediately once sand blasted for optimum bonding.
3-Rattle can of your choice for easy touch ups down the road.
I used this method on my sliders and after 3 years of road salt and grime, I still had to use the mini grinder and grind off the prime before welding when I did my
DIY bolt-on sliders V2. The primer was bonded super well to the steel. I've never seen anything like it. I've got a shop locally that will do sliders,
bumpers, etc... for arround $20-40 cash. The only catch is that you may end up with purple, grey, orange, green etc... colored primer because they use left over primer from other jobs. This is just fill in work for them. Once the bumper is put together, I'll be doing the same for a finish on it.
Cheers,
