One of the prior owners of my 71SS sprayed a lot of undercoating. They sprayed the gas tank as well as the bottem of the floorpans, frame rails, etc. I want to get some of this stuff off-especially that on the gas tank. What is the best way to get this goop off? I see that Eastwood has a product that removes undercoating. Have any of you ever used this? Thanks for any help.

Put on gloves and start wiping it down with Lacquer Thinner. The generic variety you find at Home Depot works great. At least that's what I used. If it's real heavy, you might have to heat it with a heat gun and scrape the heavy stuff off (assuming the tank is empty of course).

4 inch grinder with a cup brush works really good, that's how I did mine.

I've done the heat gun thing, and it's never failed me, just be sure you're wearing a mask of some sort. I've also heard on here that a specific oven cleaner will work wonders. I can't recall the name of it, but I know they were very explicit in that it has to be this particular brand. I also recall strict warnings towards safety gear with the oven cleaner. Something about melting thru your skin.
Best of luck,

watch the heat on the gas tank, a regular heat lamp will also work but takes awhile to warm it up, then just scrape it off with a putty knife followed by a laquer thinner wipe.

Do NOT use the Eastwood product. I bought it and followed their directions to the letter, and it was useless. Probably my biggest product disappointment from any vendor.

I just spent time doing this on the bottom of my '68...oven cleaner works great. The only thing is that it is nasty to work with!

If it's real heavy, you might have to heat it with a heat gun and scrape the heavy stuff off (assuming the tank is empty of course). Believe it or not, it is much safer to have a full tank of gas when working around it with any type of heat, even welding. It is the fumes that will explode, not the liquid fuel. An empty gas tank is much more dangerous than a full tank unless it is either new or has been cleaned out thoroughly of course. That being said, I would like to know specifically what "heat gun" is being recommended. I have to remove some undercoat also and need to buy one of these guns. Any help is appreciated. graemlins/waving.gif

Drain the tank, take it out and do it on a bench or saw horses, that way you can clean the frame area and the underside of the body. replace the fule hose section while at it.
