KBS Coatings 5400 Gold Standard Tank Sealer - 1 Quart

I purchased this product with a lot of apprehension. first I thought there's no way this is going to work!! But boy was I wrong!! This stuff is amazing... It totally removed all of the rust inside of the gas tank and my mule has never ran better! The coating went on perfectly. I followed the instructions to the letter. I gave the proper amount of dry time, I took my time with this product and it works fantastic I cannot recommend it more. This stuff is just great!! Thank you guys for taking care of my problem. My mule has never ran better and it's just a great great product.

My china grom clone had a leaking tank near the float , as is common with the china bikes. I didnt prep the tank at all besides a wipe down and letting it dry from all the gas that was left. I did 3 coats on the inside from the bottom of the tank to almost all the way up the top, and 2 coats on the outside only doing the bottom half of the tank. Each layer both inside and out was done with 8-10 hours of drying in between. The grey looks kind of bad compared to the black tank, but other than that the tank has held up with no leaks going on four months now. My gas mileage has also obviously improved immensly as a result. The can is a little hard to open and the sealant is somewhat runny so its hard to apply precisely and not making a mess. Disposable brushes is recommended and it somewhat comes out of clothes after a few washes but i recommend wearing work clothes.

Used this for the tank on my J. Deere big tractor. It worked perfectly. I even had enough to coat it twice.

This stuff Does work, BUT, after you think that you have fully coated your gas tank, removed all excess, and let it dry for several weeks… I STRONGLY recommend that you fill the tank with gas and let it sit a couple days then drain it to test to see if there is any residuals of the product left in the gas. Maybe even wash the tank out a couple times with gas and watch for any residuals. Then let the tank dry out again for several days and maybe test one last time. Residuals of the product WILL destroy your carburetor and possible you engine …

I had aluminum plates welded on the ends of an aluminum boat tank as bold down mounts to use it under the deck of a flat bed trailer. Unfortunately the welder was not a good as they claimed and left several holes that I could not get to with glue. This completely sealed the holes. As it was running out of the holes, it slowly sealed them and now the tank is air tight.

This gas tank sealer was easy to use when instructions are followed carefully. It produces excellent results when fuel tank interior is prepared properly. I used this fuel tank sealer after repairing rusted out areas of fuel tank with sheet steel patches, fiberglass resin repair and body filler to bring fuel tank back to original contour and shape. As per the instructions, I removed the excess sealer using vacuum extraction, so there was even coating of sealer over entire interior surface of fuel tank. The pictures show how the inside looks and how the exterior looks after painting and clear coating. Thanks for a great product.

After carefully following the manufacturer’s guidelines, I noticed a year later that this sealer starting to peal and chip off. Not sure if I did something wrong or this product doesn’t work. Either way, I won’t be buying it again. After the first coating was dried for two weeks in very warm weather, I gave it a second coat. Let that dry for at least a month before using it. I used the portable tank to drain my RV’s holding tanks, so it not leaking at the current time. Hopefully it only around the opening that is peaking and not down at the bottom where it was leaking from originally.

Seems like good product, haven't used yet.

Esta bueno, es un poco caro, pero es muy bueno
