Dzimm Posted July 31, 2019 Share Posted July 31, 2019 Don't use spray foam to "fix" rust. It makes properly repairing it so much worse! Thankfully whoever did this only used 1 can of foam per corner. Link to comment Share on other sites More sharing options...
DirtyComanche Posted July 31, 2019 Share Posted July 31, 2019 Acetone will melt what is left. Looks like you're going to have some fun with that though. Link to comment Share on other sites More sharing options...
gogmorgo Posted July 31, 2019 Share Posted July 31, 2019 Mine had steel put in to hold the body filler... Chicken wire on one side that fell out years ago, roof flashings riveted on the other. Guess I'm not exactly fixing it "properly" either, but 1/4"-wall tube won't rust out again, again. Link to comment Share on other sites More sharing options...

Yeah it's a mess. Up inside it all came out completely, it's just around the edges that's still stuck on so I'll probably just cut the rust out now. I've got a fire extinguisher in the shop in case it goes up. Link to comment Share on other sites More sharing options...

Pete M Posted July 31, 2019 Share Posted July 31, 2019 be careful about the steel that the 1/4" is welded to. they tend to re-rust and separate from the thick steel. Link to comment Share on other sites More sharing options...

Thankfully whoever did this only used 1 can of foam per corner. On one of my K5's I was working on a few years ago someone did that.....What a mess. Never saw something so poorly done. Seriously would have just been better leaving it rusted out. I ended up abandoning it from a restoration stand point because I found a super clean 74 cheap. I was going to make it a truggy but couldn't justify 2 K5's and my other car. Link to comment Share on other sites More sharing options...

Supposedly there's a strategy in place to address that concern. I'm not 100% on what it is, but my buddy helping me out is a professional welder with a couple decades experience who started out in autobody so I figure he's got a handle on it?

Pete M Posted August 1, 2019 Share Posted August 1, 2019 My rocker guards are welded to the frame. maybe this sort of strategy will help hold the new rocker steel firmly in place? rust is still a concern though. getting paint to remain on the inside (underside?) of the sheetmetal after it's welded up tight to the new steel is a challenge.

DirtyComanche Posted August 1, 2019 Share Posted August 1, 2019 Weld through primer and some access points to flood it with chassis saver, or something like that, are definitely needed. Seam sealing it after is also helpful... not that I ever seem to do that. Link to comment Share on other sites More sharing options...

If I run into a part I can't get to clean up and paint such as the inside of a rocker, I will paint the backside then install it with the paint still wet and keep everything as cool as possible. It will inevitably melt some of the paint but will protect the majority of it and doing sheetmetal work you have to keep it cool and go slow anyway. By doing it with the paint still wet, it has to dry out the paint before melting so it tends to keep more of the paint intact from my experience. Still not a perfect process. If there is a gap somewhere near the end of the work, it's always good to get as much paint everywhere on the inside as possible. Link to comment Share on other sites More sharing options...

Sometimes it's even hard to find rust free stuff in FL, luckily this one spent most of it's life inland in Gainesville. Having grown up in CT and having to repair my fair share of rotted cab corners, rockers, floor pans, etc. I can certainly say I do not miss having to do that stuff.

My blue truck is an Iowa truck and was rust free, although it sat for a while in a garage. Link to comment Share on other sites More sharing options...
