Gas Tank Sealer Kit For Cars is rated 4.3 out of 5 by 20.
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 5 out of 5 by from Superb, long lasting product 15 Years ago, a new gas tank for a 1969 Barracuda was pretty expensive. I was restoring a basket case that had not run in years, and my gas tank was bad rusty on the inside, so I tried this kit. It was pretty easy to apply, and it worked great. Well, 15 years later my sending unit dies. I figure since I needed to pull the tank anyway, I might as well buy a new one - they are only $130 now. Once I pulled the tank and looked inside, I was shocked at what I saw. After 15 years, the epoxy lining was still 100% intact. I could have easily kept using the old tank, but I already had a new one. Wow! This stuff works great.

Rated 4 out of 5 by from good product time will tell if it adheres well. First coat was kinda spotty, awkward 50 gal slip tank. I'd recommend saving the drained epoxy in a sealed container and let first coat cure over night. Then pour the epoxy back in and give it a second coat. My second coat looked very good.

Rated 1 out of 5 by from Bad Info! I called eastwood and spoke to there tech line about there gas tank sealer kit,asking if I could use this in Michigan because it was getting cold,-----He told me yes,well that was wrong, the stuff won't harden and the fumes were killing me,---I had to leave the barn door open because the fumes from the gas tank sealer for me were really bad!---the stuff still hasn't hardened I am lost on what to do.----I would bring it in the house but because of the fumes I can't.---So over all this was not good.

Rated 1 out of 5 by from Inadequate Eastwood simply doesn't supply enough product to treat a car tank. Similar products for motorcycle tanks worked pretty good for me, but they came with just as much stuff as this car tank kit (except they doubled the liner). With the amount of rust left in the tank I can't apply the liner... anyone want to buy two bottles of liner? The bigger issue is EW doesn't respond to voice, email or website inquiries. Maybe they should change the tag line to Do The Job Half Right.

Rated 4 out of 5 by from Great Product Kit worked great. Instructions were simple to follow. Only thing I would add is be sure to pour the muriatic acid solution out of your tank into at least a 3 gallon bucket because once you add the baking soda to it - the checmical reaction causes it to expand in volume. (much like a kids volcano science project). I poured mine into a smaller container and had overflow when I added the baking soda. Other than that, I had no problems and the tank came out great.

Rated 4 out of 5 by from Excellent Product, Super Service I am restoring a 1946 John Deere Mod. 'B' tractor. The fuel system was extremely corrupted starting with the gas tank. I took it off and followed the instructions on the "GAS TANK SEALER KIT". It took me about 7 hours but the results are fantastic. The completed job left the inside of the tank with a white coating that seemed as hard as ceramic and cleean as a whistle. I ordered the kit on a Friday afternoon and it was at my farm the next day. Super Service

Rated 5 out of 5 by from Great product to save OEM tank. Car: 1973 Triumph Spitfire 1500. I used this product to save my OEM gas tank after I welded some rust holes. Its easy to use and my only concerns were what to do with all the chemical/water rinses and what works best to seal the tank when sloshing. My tank is small, but I used the full kit as recommended. I found that nitrile gloves, zip ties and duct tape work well enough to seal the tank. You need acetone and a small amount of muriatic acid (I got it in the pool section of the local big-box home center), which boosts the cost slightly. I reserved a day to do the process but it did not take that long. They recommend using slow air pressure to evacuate the tank after you are done, I found that a small fan directed into the sender hole and out the fill hole worked great. I ran the fan for two days until all "odors" were gone. All-in-all it worked great. Make sure you do this before you paint the tank. Positives: Step-by-step process is well defined. Quality of final coating is great and smooth. Cons: nasty chemicals to play with, had to repeat acid slosh step three times to get the rust gone, maybe a stronger acid ratio should be recommended. Picture: Attached picture is post curing. note some acid and sealer marks on sender opening. Randy

will it work in the 3inch crack inside the gas tank?

Asked by: Mariodeocares
This gas tank sealer is not intended for sealing a 3" crack. It will fill minor pinholes, but not a crack of that size.

About Gas Tank Sealer Kit 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.
