Chrome rears in particular are prone to rusting underneath, not helped no doubt from abrasive road crap thrown up from the tyre. I occurred to me that the underside isn't visible unless you make a particular effort, and who would choose to do that anyway, so I started thinking about a protective coating.
That could be some kind of paint or in the extreme, something like thin rubber (I have some butyl rubber pond liner left over) glued on ...

Do any of you good folk have a view on this? Or am I looking to fix a problem that doesn't really exist?
 
I'm thinking anything is better than nothing, even if it's just paint. After cleaning, I brush painted the inside of my headlight bucket with white primer. The light color makes seeing the wiring much easier .....

For my fender bottoms, I'll be using silver probably, again brush painted on after cleaning. Luckily, my fenders will just fit into my bead blasting cabinet so I can do a nice job of rust removal. That's what I did to the above headlight bucket before painting it.
 
:agree:
I like the white primer idea - anything that helps seeing what's what in the spaghetti is good. And there's good advice in the link Gary provided for the fender - finishing with the truck bed paint seems like a good plan :)

Hi nighthog,
go to Halfords and buy a spray-on can of vehicle underseal compound.
 
OK fellas, I'm now spoilt for choice! @@Fred, are you referring to Waxoyl? That was an option I was wondering about, but I reckon I'll go with Jim's suggestion.
Thanks, all.

Hi nighthog,
not familiar with Waxoyl but any under-vehicle anti-rust/sound deadening jollop will work OK
