Undercoating

[jh99]

I know that undercoating can be heated with a torch and then scraped off, but is there any type of blasting that will remove it?

I used a wire wheel when prepping to weld in my subframe connectors(thanks Teddisnoke for your help). I came off pretty easily- its just a messy job.

Blasting will only bounce off since it's sort-of rubberized. I've had success with spraying Easy-Off Heavy Duty over cleaner on it in the evening and wait until the am to start scraping it off. It softens it enough to make it easier... I've found that wire wheel only smears it around a lot....

Is it hard to get out of cracks and hard to get places?

I removed all the undercoating from the underside of my 77. I was fortunate that the undercoating was old and dried and very brittle. I used an old 1" wood chisel to scrape it off. The stiffness of the chisel worked better than a putty knife. The car was on a rotisserie so that made it a lot easier too.

I used a few different putty knife scrapers for the mostly flat or semi-curved areas then a hammer and a few different sized screwdrivers for the nooks & crannies...

Thanks for all of the help. I am going to try to start this long process tomorrow.
