I have used this gas tank liner product many times over the years with good success. The one failure I experienced was my fault for not properly removing all the imbeded rust before applying the Kreem liner. Following that experience, I now apply a thin coating of rust converter to counteract the flash rust that forms following the acid treatment, prior to applying the Kreem liner. I consider this product to be a valuble asset for anyone needing to restore a gas tank.
I purchased this item for the first time, was told about it from a friend. I read the easy to follow directions and quickly ended up with an almost professional finish! My gas tank had many leaks around the seams and one hole risted in side of it, did 2 coats with Kreem as instructed, I would recomend this to anyone who has rusty gas tanks.
