Eastwood Gas Tank Sealer Kits for Cars is rated 4.0 out of 5 by 46.
Rated 5 out of 5 by from Good stuff I had good results with the kit, but my tank is not 100%. I have a 83 Camaro tank and it has a bunch of baffles inside of it. I had to do the muriatic acid step twice and I still couldn't get all of the rust out of the inside of the tank. The coating was also difficult to get on everything and I might not have gotten everything due to the baffles. In the end, I am completly happy, the kit was ont $50 plus another $15 for a acetone and muriatic acid. A new tank for my car is over $200 and has known fitment issues. The parts I could see looked great and the old gas smell was gone. The coating will also be a plus due to the new ethanol blended fuels.

Rated 1 out of 5 by from What warranty? Beware! After following the sealer directions to the letter we put the three tanks on the shelf for use in on going projects. After a few months the coating began peeling off and I contacted Eastwood about the problem. We were told by tech support that they had no other reports of problems with the sealer. I now see that there have been many reports of problems and that the only responsibility that Eastwood has is to return the cost of the product. This "lifetime warranty" is a joke when you consider the cost of removing the faulty sealer ($100). I am now wary of any Eastwood products since they are obviously not interested in customer satisfaction or standing behind their products. Tom Miller.

Rated 1 out of 5 by from This Product is GARBAGE! I put this in a brand new tank etched it twice and the product separated form my tank. It clogged the fuel filter and burned up my new fuel pump. I called they said it was out of warranty. I had bought it a couple years ago and just now finished the car to get it on the road so it had plenty of time to set up too. They said it was something I did wrong with it. Come to find out from some other people that had it in theirs that after the Ethanol was added it did the same thing. Any way a new pump and 2 gallons of Acetone later the tank is clean. They told me the Acetone would strip this crap from my tank and it did do that well. Just don't by the product. I would have ranked it lower if I could have!!!!

What's the difference between this kit and the POR15 sealant kit? The POR15 sealant kit has far fewer steps and doesn't require muriatic acid...What's the difference?

Asked by: allenwilson33
The Brand is the difference. When it comes to steps they do differ slightly.

I have a auto gas tank ,13.5 gallon that is leaking from rust on the out side of the tank. There is no rust on the inside of the tank. I have patched the holes on the out side by soldering them with copper plugs. Would I need to use the rust cleaner? J.T.

Asked by: Tool
If the inside is rust free you can just use the Fast etch followed by the acetone prior to applying the tank coating.

Will this product damage the paint on my motor cycle gas tank?

Some of the products used in this kit could damage your paint job. I would recommend protecting the outside while using this if you have a paint job you wish to keep.

About Eastwood Gas Tank Sealer Kits for Cars

A clean supply of fuel is critical to the performance of your vehicle - hard starting, stumbling under load, and sluggish response may be symptoms that your car's fuel system is dirty. The best way to ensure that the fuel is clean is to be certain that the fuel tank is free of rust. This Gas Tank Sealer Kit seals minor leaks and can save you a great deal of time and money in trying to locate a replacement tank. For metal tanks up to 24 gallons. Tank Tone (10030Z) resembles the original finish.


This kit includes 1 pint of Rust Remover, a 7 oz. container of Metal Wash, 2 pints of sealer, and instructions.


Extra pints of Sealer are available individually as part #10087Z. Not for use in tanks containing Nitro Methane or Aniline oils.


Additional sealer can be applied if the coating hasn't been exposed to fuel. Should the need arise to remove old sealer, pour in a gallon or more of acetone It may take up to 2 days for the acetone to completely dissolve the old sealer. If you wish to use this system on a fiberglass tank, test for compatibility by exposing an inconspicuous area to acetone to test for softening. If no exces- sive softening occurs follow label instructions but omit Muriatic Acid and Eastwood Rust Remover steps. Omit the Muriatic Acid step if using this system in an aluminum tank.


Work in a well ventilated area. Leave at least one opening uncapped when not actually tumbling the tank.


Made in the USA.


The Gas Tank Sealer Kit will seal pin hole leaks in tanks up to 20 gallons capacity. Use in steel, stainless or aluminum tanks. Sealer withstands exposure to gas and diesel fuels. This kit requires the use of 2 quarts of Muriatic Acid, and 1 quart of Acetone, available from your local hardware or building supply. Please refer to label for complete instructions. Work in a well ventilated area. Use when ambient temperature is 60 degrees F. or warmer. Leave at least one opening uncapped when not actually tumbling the tank. Allow sealer to cure at least 2 days before returning to service.
