Undercoating removal

[gmcdermit1]

I put pics of this in my project updates for my Trans Am but I figure this is where it should be. It had 30 years of nasty thick undercoating on it that I couldn't hardly work around so heres how I removed it. Other than having the whole body dipped, I haven't found a better way. I first laid down some plastic to catch the big clumps and most of the gooey tar, then saturated the whole underneath with gasoline and let it sit for about 30 minutes. I then used a high pressure industrial steam cleaner that my father in law has on it. It heats up to around 250 degrees, you can rent them about anywhere that rents equipment. I had to repeat this process a few times, but it did a great job. I then had to use a degreaser on it to get the final film off. Now she's ready to do more metal work on. I know this doesn't seem like the safest idea but it really works great. I tried many other ways like heating it up and scraping,acetone on arag, oven cleaner etc, but none of those could compare.
