so far working wonderful

I had several small leaks in an old gas tank on my Dad’s 1976 Toyota pickup. I took all the safety precautions before welding a patch over the comprised area. After welding, still small leak from but area was much more substantial. I used the Pot-15 Fuel Tank Repair, which penetrated through the welding seams and sealed the tank. I tested with air and it held 4.5 lbs of air for over an hour. Lengthy process, but well worth the effort.

I coated my DeTomaso Pantera’s gas tank in 2006 and have not had a problem at all. Recommend with 5 stars!

- POR-15 Fuel Tank Repair Kit Directions

It is important to understand each product in your repair kit and how it works. Proper chemical interaction is essential for achieving the best possible bond of the sealer to the inside of the tank. Fuel Tank Sealer does not adhere well to plastic. If your fuel tank contains plastic components inside, they should be removed before applying Fuel Tank Sealer.
