Good Evening All
It was a beautiful day in the UP today. Sunny and mid 50's. The dogs and I did some ruffed grouse hunting.
I have been thinking about the options for improving my bumpers. They are original chrome and are in good shape except for several small dents in the rear due to the previous owner's careless backing. There is of course some pitting but overall they are not too bad.
But I am considering having them powder coated. My coach and jeep wrangler are the same gold color with black trim. The only chrome on either vehicle are the coach bumpers. Black bumpers would look good.
Has anyone done this? From what I can tell, the best solution is to have a chrome shop strip the chrome and then powder coat. Anything else may not work well. The small dents could be repaired before powder coating.
There were a few coaches made with painted bumpers and if I could find someone who wanted to trade painted for chrome, it might be cheaper to prep a painted bumper for powder coating.
But again, I would like to know if any of you have stripped the chrome and powder coated your bumpers.
I know that there are bumper covers, but I do not want those. Thanks as always for your input.

Rick,
I took my bumpers to a powdercoating place and just paid for the sand
blasting. At that point, they can be filled and smoothed with body
filler just like body panels on a steel car. Powder coating is nearly
forever, and if you have any damage afterwards, removing it is nearly
impossible. Just paint to body color and it will make future repairs
no more difficult than body work. Powder coating is not magic. It
still chips, scratches and is subject to UV fade. Pics attached:

Steve,
What do you think about chrome colored powder coating?
Hey, that bow tie doesn't look like one off a Chevy?
The LPG tank looks good but I thought the gas struts supposed to be mounted
with the cylinders up?
FYI I mailed the bushing tool, you'll have it in 7-10 days (probably
sooner).

I have found that plastic body filler is in fact NOT good for repairs to metallic items when you want to powder coat them; because of the difference in conductance, the coating will be significantly thinner on "bondo"-treated areas.
What I have successfully used several times is "All-Metal" filler, comprised of aluminum powder mixed with epoxy and stabilizers. The aluminum is dense enough to conduct the high-voltage/low-amperage static charge as long as the base surface is roughed with 80 grit and the hardened filler sanded so that the epoxy skin is sanded off, allowing the aluminum substrate to do its job.
All Metal filler will not absorb any water, either (as plastic filler does immediately).

If the bumpers are stripped back to bare metal then repaired they need to be
plated to prevent rust as powder coating is pourous and the rust will
develop behind the coating and you will have bubling of the surface, avoid
body filler if possible it can react if the heat of the oven for curing the
powder coat is high.

That is one of the reasons I was advocating just painting them body
color Mark.

Cyls down Rob. Works perfect.
Tracker sold for $6,500. The guy never came back for the Alladin
adapter pins so I now have an extra set.
