anti rust rubber removal in qtrs?

[xe1984 64]

Any tips on how to get rid of all that rubber crap in the rear quarters that's suppose to prevent rust. Want all gone so I can weld in sections.

Two methods : mechanical and chemical. If you want to remove small areas, a common or garden variety paint scraper or spatula will do the job. That's the "mechanical". You can use a heat gun to soften it some more if necessary. As the stuff is bituminous/oil based, you can remove the residual with oil/grease remover (prepsol) - but it can get a bit messy.

 

My method of choice is to remove the bulk of  the material with a scraper, abrasive blast the remainder, then prepsol the remnants. This provides a paint-worthy surface. If you're not aiming to repaint the surface with anything else except the same stuff, your degree of prep can be scaled back. If you just looking not to set fire to the stuff whilst welding...scraping and cursory clean should be fine.

Would dry ice work for this like peeps use for the sound deadener? Just a thought, could be a lil less messy.

Yeah the dry ice will be to hard as I have cut out bits so there holes for the ice to fall through and I want it all off the walls too.

Thanks Gav for your reply, I might have to do one of them. I'm trying avoid hanging down in the boot to long as I get the worst back spasms.

I used paint stripper, scrape and wash with thinners. Messy job !
