Product Overview:
Description
Renew old tanks in cars, trucks or motorcycles using Eastwood's Gas Tank Sealer.
This special formula seals pinhole leaks and prevents the formation of rust inside the tank. It also resists alcohol and fuel boosters for longer-lasting protection. Our liquid gas tank sealer can be used on all steel or aluminum gas and diesel tanks. It works on some fiberglass tanks, too (see details below).Gas Tank Sealer should not be applied if you use fuels containing more than 10% ethanol, as this can degrade the sealer. Please contact our experts if you have questions about whether this sealer is right for your tank.
Instead of searching everywhere for a hard-to-find tank, use Eastwood fuel tank sealer. One pint of sealer treats tanks up to 12 gallons capacity. This is the same sealer found in the Eastwood Gas Tank Sealer Kit for Automobiles; order these bottles if you have a larger tank, already own the needed prep supplies or want to seal a freshly-built custom tank. Visit the Eastwood Garage for a full tutorial on How to Seal & Restore a Gas Tank or contact our DIY experts for more information.
How to determine if Gas Tank Sealer can be used on a Fiberglass Tank.
Some earlier FiberglasTanks (generally pre mid-1980s) did not have a complete gel coat on the inside of the tank. Without this gel coat, the Gas Tank Sealer and the required cleaning would potentially soften and degrade the fiberglass tank.
Newer tanks ( since mid-1980’s) fiberglass tanks typically do not have this issue because they have a gel coating inside. To confirm if your fiberglass tank is compatible with the Gas Tank Sealer, look inside tank with flashlight. If the inside of the tank is smooth, the sealer should be fine to use. If they can see strands or the actual fiberglass matt, then you are not able to use the Gas Tank Sealer.

Application Tips
Use this in properly prepared metal gas or diesel tank. See label instructions for surface preparations. Works best when ambient temperature is 60 degrees or warmer. Use these products in a well ventilated area, or wear a respirator like our Pro Respirator (34029). Allow sealer to cure at least 2 days before returning tank to service. Not for use with fuels containing Nitro-Methane or Aniline oils. Ethanol blended fuels may adversely affect this sealer. For best results, do not use with E10 - E85 fuels. Not compatible with plastic gas tanks.

Good product
this is a case of read the directions and read them again. I did and it seems to turned out good. A word of caution, after treating I left the tank in a closed area. It lefted the paint off the outside of the tank.

Had my doubts but it really WORKS !!!
I have a diesel tractor that is 45 years old and while it runs fine, it started to have a fuel leak at the tank. I pulled the tank and found out that I wasn't the only one who had seen this problem before. The bottom of the tank was covered in some form or epoxy that had been placed there in the past but was hidden from view when I purchased the tractor. I cleaned out the rust using the Diluted Muriatic Acid wash and then etched it as recommended. After flushing it out with Acetone, I plugged the drain hole and fuel supply line feeds and poured in the Eastwood Tank Sealer. I rotated the tank and completely coated the inside in about 2 minutes and then set the tank standing up straight and opened the fill port. Looking inside it looked like a newly painted white boat hull or a porcelain coated pot. The coating however slowly thinned on the sides, moving to the bottom thanks to gravity. The fumes coming out of the tank were pretty strong. I was in an open garage but that wasn't sufficient so I got a squirrel cage fan out and set up so that it was blowing across the tank moving the fumes completely out of the garage. In doing this I noticed that the tank coating fluid began to "set up or cure" much faster, so I closed up the tank rotated it again and then exposed it to moving air again. I didn't use the air compressor concept they tell you to do in the instruction as the fan delivered sufficient air across the tank fill opening to make it sound like a distant steamboat whistle. But moving the fumes out of the tank with the air movement, I was able to quickly rotate, coat, expose to the air flow and get the sealer to more quickly coat and stay in place. I found found that the quicker I exposed the sealer to the air stream of the fan the faster it was setting up. At one point I found that it was setting up a little too fast so I capped off the tank and let it set for about 5 minutes and after doing that the remaining sealer was quite easy to move about and finish coating the remaining area that were thinner than the others. I finally got to the point were the sides were completely coated and pure white and had cured enough to be stable. I then let the drain plug on the bottom of the tank open and drained the remaining sealer back into the original bottle. After 2 days of squirrel fan air flow over the open fill hole, the tank was a beautiful white. I tested it with a full tank of diesel and let it sit for 5 days with not sign of any leakage at all. I am more than pleased to have found this product and would recommend it to anyone who need to fix a leaking fuel tank.

Just got a NOS tank for my SuzukiGS550 in the original Suzuki box and the inside is gleaming new - no rust, grime or anything. Question - since there is no rust, oil, gas, etc do I have to pretreat the interior before sealing? THX
Actually, while etching may not be neccessary, yes there is prep needed on new tanks. All smart companies that make/fabricate metal vehicular parts, that can not be primed because of the type of part, coat them in a product to keep them from rusting. This product is called Cosmoline and is used parts ranging from brake rotors, fuel tanks and pumps, steering and valve train / cam components. On a motorcycle tank I would pick up a gallon + 3 cans of carb cleaner, a 32 oz bottle of alcohol. Now this might sound weird but I would also grab 2 - 16 oz bottles of 100% acetone, not from the paint department but, from health and beauty!! I buy that because #1 it's much cheaper and #2 because the fact that it is sold for use on the human body, it actually has to pass rigorous testing to prove it is what it claims. Meaning you get a purer product. How I would clean a new bike tank: First cap all holes/lines, half fill with hot water, shake for couple dump, spray can all line ports including air breathing one then recap, pour gal carb cleaner, shake 3, let rest 30 rotating every 5 so bottom, top, sides, back, front soak in it. Repeat 4 times & dump into bucket in case needed again, rinse. Pour Acetone same as carb except only 2x, rinse. Now alcohol shake 5 - 10 depending on size/shape of tank & dump. Leave all ports open, the alcohol is for 1 thing, to dissipate water so don't rinse after as it will be completely gone in an hour or less.

I have several plastic gas tanks from some vintage Moto Ski Mini Sno snowmobiles. All are badly cracked. Will this or any other sealer you can recommend, seal these plastic tanks? I have tried plastic welding with some success but a sealer is preferred.
Unfortunately we do not have a Plastic gas tank sealer option at this time.
