Does anybody here know of a good way to remove 28 year old undercoating without sandblasting??
you are talking about that rubbery gouye stuff right?
well sandlasting won't help much because the rubber dampens the effect of the sand to much, unless you put the thing on full blast and that can cause some other problems.
I do have A LOT of experience with this stuff
(I hate to say!) and if it dryed up your in luck because you can easely scrape it off then.
if not go get the heatgun and heat the stuff up (it will soften the stuff)and then scrape it off.
afterwards I clean the residu with good ol' gas.
and if somebody has a beter plan I WOULD LOVE TO HEAR IT TOO!!

yea i was just gonna say... gasoline will do it.
i undercoated for 8 months at a dealership and the only thing i could use to get it off my arms and glasses was gasoline.
Varsol doens't even do it unless the stuff is fresh.
My sugestion would be to put some gas in a spray bottle, spray it on the undercoating and let it sit for about 20 mins. it will become like butter. Depending on how thick it was put on you might have to go over it more than once. Either way, it's gonna be a very messy job.

Fortunately the stuff is pretty brittle, so I've been scraping it off with a sharpened putty knife. The main reason I'm taking it off is for rust repair. Going to seal the rust with POR-15 and use interior sound proofing. But noise is the least of my worries as it's a convertible and it won't be driven in rain, snow or other bad weather. Thanks for the feedback.

I had to remove an undercoating type substance that someone had used in a failed attempt to seal a leaky gastank. I say undercoating type substance because I do not know if it is the same thing that you are up against. However, when the gasoline, diesel, lacquer thinner, and acetone failed I tried a floor adhesive stripper designed to strip mastic. It worked like a charm. Brush it on, then wipe the stuff off a few minutes later. You can get the stripper at lowes, home depot, etc. It may not work in your case, but it sure beats scraping if it does. By the way, it also strips paint and will burn your skin so be cautious.

As you can see, it's been 3 months since I started this project. Low and behold, it's been quite a job, but it turned out great. The undercarriage looks almost new: nice, clean, black and without rust. As soon as the humidity clears here (sometime next month), I plan on dropping the gas tank and doing the last few patches. POR-15 is easy to work with and has given me excellent results! Now, get a new top and I'm in business !
