All,

 

Forgive me if this has been asked before, but I wanted to get some advice. I pulled a set of bumpers off a Series 1 parts car to replace the bumpers on my own Series 1. The bumpers I pulled off look good, but do have some surface rust on the interior/car facing side. How would you recommend I prep the bumpers prior to putting them on my driver?

 

Thanks!

 

When I did mine, I used a wire wheel attachment on my power drill to thoroughly clean the inside of the bumpers of any corrosion, then bought the POR15 starter kit & used the cleaner and metal prep, then applied the POR.  Tape any holes in the bumper to prevent it getting on the chrome surface.  After it dried, I painted over the POR with a gunmetal grey paint.

Came out great.

+1 on the process described above - its exactly what the paint shop did for my bumpers.

Replate them

If you have them re-plated the shop will usually prep and seal the inside surface as well.
