I have spoken to a number of people who have used it successfully. One eldery fellow had me stop by his farm and look at an old case tractor he painted with the KBS. All he did was pressure wash it and then used their metal prep on it. The tractor sits out all the time and the paint work was about 2 years old. It was ugly looking but no rust. A friend of mine also hooked me up with one of their tech guys...he sold me on the stuff.

i own a 71 moto guzzi that I've been painstakingly rebuilding, well i sent the gas tank out to be pressure tested and sealed prior to doing anything on the bike, i got it back and you could see the coating, well after several years and getting the bike painted we got her back together and on our maiden voyage we discovered a leak in the tank well what can i do it's been several years sense i had it painted well a friend told me of your product i purchased it and after following the directions to the t i can't be any happier i would and do recommend this product to anybody that has a leak.

your truly a very happy gonzo

I had pinholes in an old motorcycle gas tank. This was a great product, less expensive than the white sealer and worked as advertised. It was easy to apply and am happy with the results.

I could not be more pleased with your product. I read up about tank sealers online and the large majority of post I read recommended KBS. The instructions were easy to follow and if you take your time you will have a tank that's good as new.

I own an independent Harley Davidson motorcycle repair shop. I have used KBS coatings for a long time and have found your products to be way above the rest.

At the present time I am working on a 1953 Indian Chief restoration. Someone previously used and inferior product to seal the tank. Needless to say it is peeling off inside. I have full confidence the KBS stripper will remove all the old sealer, so I can properly re-seal this tank with the 3 step process. Thus allowing this old Indian Chief to roar to life once again.

I wouldn't trust anything else but KBS for this valuable antique.
