How about another rotten rocker panel brainstorm?
A couple months ago I noticed a rust bubble between the back door and whel well so I got the grinder out this weekend and before I knew it I had the rocker trim off and I was staring at a bunch of rust under the back door. Front door actually looks pretty good.
I ground off most of the crap metal, sprayed some rust converter on it, and a couple coats of primer to get me by for a while.
Took it by the body shop today and he said $300 to weld in the replacement rockers (supplied by me - they're pretty cheap, $25 per side) and paint it.
Sounds like a fair deal, but as usual - now I'm thinking I should just tackle it myself.
Given the location - appearance is so unimportant it seems like something that would be pretty hard to mess up bad enough for it to matter.
I think one of the hardest steps to get right would be locating the holes correctly to allow the trim to snap back in place.
My main objective would be to clean it well enough, and protect it well enough to keep it from rusting at least for the next 3-4 yrs.
He described the prep process to me and as I understand it he basically expects me to have it prepped before I take it back to him. He explained where to cut the bad panel so it could be replaced and welded with a new piece.
I have done some basic welding before, but I would have to acquire a welder. I might be able to access one at work for a few hrs.
What about coatings before/during installation?
It seems like it would be wise to coat the new panel before welding it in place, but I don't expect any coatings around the weld area to fare well.
