My 10 yo helped me clean the inside of the tank. I had a lightly rusted area about 2"x 2" that came off easily. Should I coat this tank or just leave it bare?

Best way to remove rust from a gas tank/ / / Go to home depot. . In the cement section they have a gallon jug of cement etching acid. it's around $12= green color if I remember correctly. . . . it's really phosphoric acid. . . mix it 2:1 with water, , slosh it around in the tank for 20 - 30 minutes. . it will convert the rust and clean everything else bright steel. . rinse with baking soda and water to neutralize. .
if the rust is heavy. throw in a hand full of small screws and washers. . shake the hell out of it. . . I made a sling from a tree to support the tank, and all you have to do is rock it around. . the only prerequisite is that the tank needs to be substantially good meaning not almost eaten through from the rust. . and then you need to figure out how to dispose of the waste. . |
