Rating Slick finish but I made a mess
 
It's a good product with easy to follow instructions. I only had two things that slowed me down. Living in the desert and trying to find a time frame where the temperature was cool enough was tough in August; when afternoon temps hover over 100 deg F. Also, draining the excess sealant out of the tank was very messy. Neither of these things keep me from recommending this product. I'm very satisfied. Thanks KBS.

As long as you follow the directions it works great. I had some problems with it drying but it got better once I got a fan to dry it.

Rating Great product !!!!
 
The complete 3 step system was easy to use and the process was extermely effective to resrore a very badly rusted Jeep gas tank. I should have used your external coating for the outside instead of fiberglass. Instructions are easy to follow. You need to get this certified for aircraft.

Rating Search no more for a fuel tank sealant
 
I had a fuel tank that 3 repair shops told me was junk and that I would need a new one. I tried this product for the first time and couldn't believe how well it worked. It sticks so well it took 2 weeks for it to wear off my skin when one of my gloves broke so wear strong gloves. It can be messy, but thats what it takes to coat and entire 18 gallon tank top to bottom. I would recomend this product to anyone Amature or Professional

Used on a steel diesel tank for a tractor. Had the seam welded by a professional and it still leaked. This product cleaned the tank very well and then sealed the leak. Would use again no question.
