Snowing like crazy here in Wisconsin today. I got bored and headed to the basement. The old girl looks a little different.



That rust pile came out of the mufflers



I need to get my Fluke out and check some continuity in some wires this looks like the only bad spot



Taking the gas tank to work to clean out some fine rust and a tiny amount of shellac. I will start with simple green then vinegar if that don't cut it some paint thinner will
all diluted with some hot water

Grab a handful of old washers and small nuts, pour them in the tank. Seal it after adding about a quart of Diesel fuel. Roll it it your hands. You will feel the metal rolling in the tank. After about 20 minutes, unseal and drain the whole mess out. Let it dry. Then add some Muriatic acid and seal. Rotate 1/4 turn about every 4 hours for a day. Rinse with a hose,dry with air, then fog it with WD-40 until your ready to add fuel. You can POR it after that if needed.

Guys, don't mess around with all that nasty, toxic stuff. I have used Rusteco on rusted tanks and it works great. Won't harm paint at all like the acid etc. Won't harm you or your skin or eyes either. This stuff works great. The U.S. Navy uses their products.

My old tank doesn't have much rust. But it has a shellac-like deposit on the bottom.
What is the main ingredient of Rusteco? We have some bio degradable heavy duty cleaner at work. I would like to compare the list of ingredients if that is possible.
thanks

Ole, I'm not sure about the ingredients, but if you go to the link I included it should give you all the information (http://www.rusteco.com/). That old tank has a really nice patina to it with what looks like the original paint, I'd hate to see some of the paint get eaten up with the acid if you have a whoopsie when you're removing the rust. The RD400 I restored had all kinds of gunk and shellac in the bottom and the Rusteco got it all out.
