Tank Sealer Overview

Gold Standard Tank Sealer

Gold Standard Tank Sealer is a superior, single component, ready-to-use sealer formulated for coating the inside of metal, aluminum & fiberglass tanks.

Widely recommended & easy-to-use, this single application coating cures into a tough fuel impervious seal. The entire tank including pinholes & weld seams are permanently sealed to prevent the return of rust & corrosion and clogged carburetors.

The Tank Sealer's rock hard finish remains flexible to withstand vibration and the repeated expansion & contraction of the tank! Other sealers are little more than paint or adhesive-type coatings which have poor sealing abilities especially when exposed to today's fuels.

Wisely choose Gold Standard for an incredible long lasting seal! Satisfaction guaranteed!

Q: I have to seal just the base of a tank only. Can I coat part of the large tank with the Gold Standard Tank Sealer or is it necessary to cover entire interior?

Asked by:  - 12/27/2014

A: It is always best to coat the entire inside of the tank. If you do not, you do run the risk of the Tank Sealer delaminating (peeling away) over time at the edges.

Rating Hard durable finish that will last
Removed pitted aluminum tank from my sailboat and installed a built-in tank out of fiberglass. Just used the sealer to coat the inside of the tank with a foam roller. Seeing it a week later after the full cure and seeing what's left of the roller I used, I'm sure this tank will last forever. It's a hard finish that even has a smooth glossy look to it. So far, I'm happy with this product.

Rating Perfect amount to get the job done!
This was the perfect product to seal my messy gas tank! I had a ton of rust and an old liner that was peeling off the inside of my tank. I used paint stripper and shook around a bunch of nuts and bolts to get the old liner off and then used white vinegar to remove most of the rust. Then when all was dry and a little bit of rust was speckled here and there I used this product and it came out beautifully. I did it on a 4-point-something gallon tank and it was the perfect size can to get the job done. Very pleased. Only negative I had for it was that it kind of gunked up in the hole where your fuel hookup goes. But as my tank had a lip on the top fill hole I had to use this as my drain location so I can't really blame the product for that. Could have moved it around a bit more.

Rating great stuff
this stuff is great. plan ahead, and over plan. the first step leaked due to my under estimating of liquids. the second and third steps did not leak. if you place bolts/nuts/change in the tank for step one, tie them together. it took me over an hour to get them all out. COUNT them first, as i did which at least helped me in the process. i used the remaining sealer once drained to coat the outside. perfect, but sticky prepare and have a clean up plan. its hard to get off of your skin otherwise.

Rating Be careful about coating thickness
Used the complete 3-step kit. Took a LONG time to blend the pigment evenly. Viscosity good; coated tank interior well. Used leftovers to paint outside of tank. Any place with a thick coat blistered due to gas entrapment, and had to be shaved off. Looks to be very durable. Seems to adhere very well. Appears to be very very tough when cured.
