Gold Standard Fuel Tank Sealer is a superior, single-component, ready-to-use fuel tank sealer. Gold Standard Fuel Tank Sealer is specifically formulated to stop rust and corrosion by forming a tough, fuel impervious coating while simultaneously sealing small pinholes and weld seams. This kit contains our KBS Klean (a water-based, heavy-duty, cleaner/degreaser) and RustBlast (a powerful rust remover/metal etch) to obtain a permanently sealed, rust-free fuel tank. These KBS prep products are formulated to extend storage times by leaving a zinc phosphate film.

It seemed like a long process, but it works. I had a 20 gal Corvair tank that had been sitting for 38 years. Pretty ugly inside, so I washed it out with a quart of lacquer thinner first. Be patient, follow the instructions and make sure the tank is rust free and dry before the last coating. Shop vac works for that. After you dump the unused sealant, keep rotating the tank so it doesn't puddle, so leave yourself plenty of time for that. I dumped out about half a qt of used sealant, so you can paint it on something else, like the outside of the tank or anything else you want to protect. It is about as hard as fiberglass when completely dry.

Product seems to be working well and for sealing the inside of my diesel tractor tank. Instructions were clear and easy to follow.

Works like a charm when you read the instructions. My leak was pretty large and in a tank seam.

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.

questions asked on late Friday were answered on Monday. Almost couldnt believe they called back. Worried about wrecking a 3000 dollar paint job on my motorcycle tank. Was advised as how to cautiously proceed. Just excellent service and product did its job. Looked like a brand new tank inside when finished.

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

There are some incorrect reviews on here saying you get 1 gallon of sealer: you do not. you get one pint. The kit comes with a direction card which is CLEAR and good. Before getting the kit I soaked the tank with Vinegar and hooked up a rig to rock it in a pair of ratchet straps looped over a fender stand. I would rock it twice or so an hour as i worked in the shop and let it sit overnight. i would then come in in the morning, turn the tank and repeat for another day until after a week, the tank had been cleaned. the cleaning job vinegar did was superior to the job done by the cleaner in the KBS kit. With this kit, I used the cleaner in a second tank along with BBs. The cleaner is Sodium hypochlorite relative like 409 or other commercial degreasers and cleaners. I followed the kit cleaned tank with a rinse and then used the zinc phosphate, turning the tank completely so all sides got exposed for 3 minutes followed by sitting it down for five minutes. I did this 12 times so that each side was cleaned and soaked twice and the process took almost 2 hours. When zinc was done I emptied the tank and rotated it until no more would come out. When this was done, i used a heat gun to gently dry the tank and I let the tank sit for two days in a low humidty air conditioned room. After I was sure the tank was dry, I poured in the sealer and rotated the tank on a timer for 3 minutes followed by 5 minutes of rest, with fluid being left to rest on a new side after each rotation. i did this six times so that the tank could rest on each side. When the rotating was done, I poured off the remainder into the can and found I had more than half the can left. From the can I brushed all but one side of the tank to the tank was completely painted with the sealer. Inside and out have a nice glass like tough coating. I am hopeful it lasts!
