The consensus here to removing undercoat is heat gun and scrapper. Can I remove the undercoating from my gas tank while it's still in the car with gas in it or am I looking to create a mushrom cloud? Thanks Pete

Eastwood make a spray that helps remove the undercoating. I haven't tried it yet.

A heat gun will work. If you're worried about an explosion, Just fill up the tank full of gas and you'll be find.... I HOPE!!!


Seriously, an empty gas tank is more explosive because of the gas vapors and more oxygen in the tank. A full tank has little air and oxygen because the gas displaces the air. Fire needs oxygen to burn.

I recently completed this job.
It was not so difficult. I first drained all the gasoline. Then I used Eastwood undercoat remover system ( WORKED GREAT). after all this I used my mini grinder with a wire wheel to really clean the tank.
My next step was to take care of the inside of the tank. I used Por_15 tank cleaner / sealer system (eastwood has one too. )\
After all this work I sprayed Eastwood gas tank paint.
The tank looks NEW.
Take your time and do it right and you will be very pleased.

Someone on this site said to use diesel fuel in a spray bottle and let it sit for a few hours. It's probably cheaper than undercoating remover.

I just used some regular old paint stripper (Red Devil brand) - worked great. Turned the stuff to snot and just wiped it off. Think I spent about $2.97. I'm sure the shipping on the Eastwood stuff runs more than that. My $.02.

I second the last post. I did the same thing - bought some stripper at Home Depot that worked on asphalt-type products. The tank cleaned right up.

I'd go with the stripper route since there's fuel in the tank. It'll save you time and maybe a fuel spill. Using Eastwoods stripper may be a little messier than scraping it off but you won't have to worry about the heat. I wouldn't put any heat to the tank with fuel in it. No matter how much there is. You're just asking for trouble. And if you can, strip it while the car is outside.
Always have a fire extinguisher handy when you're working around a gas tank!!

Good luck!

I have chimed in many many times before regarding this issue. Try diesel fuel. Spray it from a bottle and let sit for a day. It comes off like butter. After the majority is off apply a second or third coat and rub with a scotch brite pad.. Bingo !! I have done two complete cars with this process and nothing beats it. But as always use extreme caution as this stuff like many other petroleum based products are flammable. Put out any open flames and keep the lead light away. Try it you will be pleased !!
