KBS Coatings 5200 Gold Standard Tank Sealer - 8 fl. oz. by KBS Coatings

Used on the inside of a briggs and stratton, five horse gas tank stuck to the metal grate.But there was plastic inside, and it all peeled off. Using in metal, only gas tanks give it to thumbs up

This product worked as expected. Made a good job on a very Rusty 75 year old tank

Great product

use in a radiator tank to seal leaks, so far it is holding

Does the job for a little less money. Unfortunately, it didn’t seal all the pinholes in my tank, but that was likely due more to the horrible tank, I was trying to seal, and the prep not being sufficient.
