KBS Coatings 53000 Auto Fuel Tank Sealer Kit, Seals Up to 25 Gallon Tank

My gas tank was for a 1978 International Scout II that had been sitting for a decade when I got it. The tank was nasty and had some pinholes. First I drained the tank, cleaned it with degreaser and an old chain, then de-rusted it with electrolysis. There are some videos on youtube to show how its done. Then I broke out this sealant kit and cleaned it again. The gloves that come with this kit are worthless. Get some good, thick rubber or kitchen cleaning gloves for this project. Also, get a couple walmart or bread bags to put over your shoes when using the sealer. I spilled it on my feet and I'm waiting for it to wear off. The cleaner is a powerful degreaser so I drained it and saved it to clean the engine with later. I followed the instructions precisely, except I missed the statement to NOT allow the Blast primer to dry in the tank. I did save the primer when I drained the tank, so the next day I re-Blasted it again, then allowed it to dry. I used JB Weld on the 5 pinholes, which were really just pinholes before adding the sealant. The instructions say not to let it sit in the tank for greater than 30 minutes, but if you are in a high humidity area like I am, it really should sit in the tank for much longer. You have to keep rolling the tank to make sure it is fully coated and does not get too thick in one area. I made sure the seam and the bottom of the tank were well coated before pouring it out into a bucket. I then hung the tank and painted the outside of it with a chip brush. I also cleaned, primed and sealed the metal fuel filler tube from the truck. There were a couple places on the outside where I got it too thick and it bubbled up and separated from the tank after it dried. I can see where that would be a problem, so make sure you do not let it set too thickly on the inside. Gotta keep rolling it every 5 minutes until it is dried. I did it inside my garage with the fan blowing, you have to have ventilation for this project. Plan on waiting 4 days to put fuel in it. I let it dry, then filled it with water and did a pressure test, it passed sat. Let it dry again and installed the tank. I like this option much better than spending over $350 for a new aftermarket plastic tank.

Every steel tank should have that coating on as a preventive for damaging rust.

This is great stuff I put it in a gas tank out of 1925 Chevrolet Superior k And work like a champ Is exactly what I wanted it to Little hard to work with But it did what it was supposed to do

Great product.
