Reviews

Read reviews, read company literature, ordered the product and applied it to my 65 AMC Rambler American 330 station wagon gas tank. Went on well, flowed evenly with putty knife. Dried as reported. Painted over with no issues. Not back in the car yet but I have high hopes after seeing it on the tank!!

This stuff worked great! As described. Just follow the instructions on the package. I used a caulking gun to dispense the product, It should be mentioned with the product that a dispensing gun is needed. Fortunately, in my research about applying the product, I discovered that a caulking gun could be used.

This isnt the first time that I have used this product on my RV8. Fuel tanks just seem to be a pain on any aircraft. This stuff is gooey, stinky, sticky and just plain nasty. HOWEVER, it works and works well. Its very competitively priced in comparison to the other brand, and I dare say, just as effective. I highly recommend Chemseal when needing to seal, or reseal, your fuel tank.
