Megaton Posted March 18, 2017 Share Posted March 18, 2017 I, like a lot of you, have rusty rocker panels. I found what might be a cheap repair on YouTube. Expanding foam is used to backfill the area then tiger hair or equivalent is used for the final contouring. My question is, if the rocker is sealed up with foam will it cause drainage problems and start rust in a different area? I plan on coating the inside of the rocker with an internal frame spray to convert the rust and prevent more. I also have rust spots around the rear wheel wells that this might work on. Any feedback will be appreciated. Link to comment Share on other sites More sharing options...
colinnwn Posted March 18, 2017 Share Posted March 18, 2017 That expanding foam stuff eventually turns into a sponge and causes more rust where it is sprayed, and by diverting water to other areas as you surmised. Sorry I don't have alternatives. But I'd live with the rust instead of spray foam. Sent from my Nexus 5X using Tapatalk Link to comment Share on other sites More sharing options...
Bunchie Posted March 18, 2017 Share Posted March 18, 2017 Yeah I would 2nd that idea...got abuddy who owns a autobody/restoration shop & he sez the ONLY way to deal with automotive cancer is to remove it completely and replace it w/new sheet metal(and they do a LOT of it). I realize that may be financially impractical for you but there products like Rustmort, etc, that will, at least, halt the spread of the rust. Consider checking out high school auto shops...sometimes they will take on outside projects simply for the chance of the students being able to work on a different vehicle other than the few thay may have been donated to the school. 2 Link to comment Share on other sites More sharing options...
Megaton Posted March 18, 2017 Author Share Posted March 18, 2017 Useful information. Now for Plan "B". As soon as I come up with one. Thanks everyone. Link to comment Share on other sites More sharing options...
PathyMD Posted July 9, 2024 Share Posted July 9, 2024 Ever come up with a solution? Dealing with rocker rust myself and local auto body shop is just saying its not worth the money... Might just see if I can find someone with a welder to cut out the rusted metal and patch it with sheet metal. I need utility more than aesthetic.

Megaton Posted July 15, 2024 Author Share Posted July 15, 2024 No, I haven't found a solution I can live with yet. Something else always becomes a priority. Your solution is as good as any I've found. A place called Noram has replacement body panels at a decent price. Might be cheaper than plain sheet metal. Hope this helps and good luck.
