detoursUSA and rust

This question is for you guys with the detours rear bumper: Has anyone had any problems with rust under the quarter guards? Whats a good way to prevent rust when I install the one I have in the garage?
thanks

I have been around heavy duty bumpers for near 40 years. For the longest time rust was just a common occurence. Most recently with the advent of spray-in bedliners bumpers that we used to paint now get bedlined. My aftermarket front and rear bumpers have been coated for 6 years with no regrets.

If paying to get them coated doesn't appeal to you then maybe you can do a combination of rust oleum and herculiner for a substitute.

Your bumper was properly prepped by being sandblasted prior to primer-
sealing, the primer/sealer is applied thru a spray gun, its not rattle can
and is a professional automotive product. The primer/sealer itself is a
strong defense against rust although farely UV sensative, so it fades
and looses characteristics if not top coated.
Use an oil based paint at the very least to top coat, apply additional
coats to the inside of the bumper if you feel your in a hard core rust
area......do the same to your lower rocker before install if you feel
its required.
After install, run a nice bead of black silicone accross the top of the
rocker protection area, you'll hardly notice the silicone. Do not seal
the bottom of the rocker area, you dont want to trap potential problems,
it best to let the area breath and allow particals to drop out rather than
lodge...
Proper prep is key.
Dont apply heavy bedliner to the inside of the rocker panel protection,
you'll never get the bumper in place, it fits 'that' snug.

I second this, plus the front leading edge of the 1/4 guards. I just did this on my 98 with the C-rok rear bumper. When I pulled it off to re-paint I had some bad pitting and rust on the lower 1/4's. So after prep and re-paint, I ran a bead of silicone around the front and top of the 1/4's and well have to wait and see what happpens, hopefully cured or at least lessened the rust problem.

My apologies for the bad advce. I'm not really that familiar with the product in question and should have kept my thoughts to myself. For other bumpers that I have owned the bedliner works quite well.

not really concerned about the bumper. I was referring to the lower quarter panels. I will add a layer of paint on the quarters, and seal with silicone. thanks
