Well I have finished cleaning the rust out of my fuel tank and sealing it. I used the por-15 automotive fuel tank rust remover and sealant product. I give this procedure a thumbs up. But i do have to recommend using muriatic acid before actually using the por-15 because it is what actually got rid of most of the rust. My fuel tank looks perfect now and has no signs of rust whatsoever, sorry for no pictures but i have yet to get my digital camera installed. And as always, whenever using the por-15 products or any acid type materials, do get gloves and goggles. I would recommend this product to anyone with a rust gas tank but I would actually say that if you can get a good tank for cheap, go ahead and just get a new tank, this procedure is very time consuming and stinky. Also my mom doesnt like the 10x10 circle of dead grass in the middle of the back yard lol. Any questions?
