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

works like it says follow the instructions

This product has a fine reputation for a reason it works. However you’ll need the tank etcher to complete your project.

The quality of this product is really good and just this small can filled up my full sized motorcycle tank. If you plan on using this after cleaning out a rusted tank let me help you out so you do it the right way. Use evaporust from oreily and pour half of the bottle in the tank with some nuts or bolts to loosen up the rust. I'd start my shaking it a lot and then let it sit for about 20-30 mins on each side of the tank, shake again, and pour out. Add the other half and repeat the process. (Remember to save this stuff for later it's reusable) After you've done that get lots and lots of hot water and rinse out the tank about 4-5 times. Swoosh is around a lot to break free all the left over bits of rust. Once you've completely flushed out all the chemical and the water is coming out clear completely drain the tank, and grab yourself a heat gun or a blow dryer (which is what I used) and hold that boy over the whole of the tank and let it dry dry dry. Check inside after a few minutes to see if it's still wet but obviously the longer the better (DONT RUSH THE PROCESS) Once you're fully confident it's try use this sealer, mix it up a bit and then pour it in. Use a funnel or what i did was roll up wax paper in a tube and used that as a funnel. slowly turn the tank in all directions and let it cover the inside. Let dry for 30mins to and hour and kaboom. Nice and ready to go. Hope this helped someone in need✅

works well..had to seal new oil tank that came with welding slag still in it small metallic pieces couldn't get it all out coating covered great..go to manufacturer page and see the right way to use

Used as part of the three stage sealing for a gas tank. This was an easy process. There are ample videos on the internet that share how to use this product. There appears to be product left over which I will likely use on another gas tank project. It is still early in the process and I hope this product will address the issues I have had with a rusty gas tank contaminating the fuel delivery process with a combustion engine.
