KBS Gold Standard Tank Sealer

2022 Pan America. I bought the kit to coat my aluminum tank in order to prevent early fuel pump failure. Let me say this kit is amazing! The cleaner is top notch, just wear gloves. The etching compound is evident due to the color and texture of the aluminum tank. There was residue from the aluminum welding. that the cleaner removed. The Etching compound turned the aluminum white and provided a clean dry surface to adhere to. Finally the epoxy coating is amazing. The coating is enough and instructions are very clear and concise. Follow them to the letter.

Awesome

I used the KBS large tank kit on a 1986 Yamaha FJ 1200 that has been sitting in storage for 24 years with some fuel left in in the tank. The 2 first stages cleaned the rusty tank so well I could see some bare metal. The coating stage did a fabulous job. This product definitely saved my tank for many years to come.

Awesome Stuff

I used the KBS Strip to remove a failing tank liner from another popular company and this kit. It works like a charm if you are patient and follow the instructions. Don't rush it. It cleaned and prepped the tank to like-new condition. The sealer dries rock hard and is holding up well. Will use KBS again.

I used the cycle gas tank clean & seal kit. It arrived extremely fast. Cleaning the tank was easy, not messy. Read the instructions and use the products as instructed and the results will be perfect. I ended up with 2 gas tanks perfectly clean and sealed. Was very easy, results great and I didn’t have to be overly worried about the tanks finish paint job.

Before and after repairing a seam leak

I had a seam leak near the back of tank where the bottom of the tank is roll welded to the upper section. I followed the instructions taking my time to complete the process. There was very little rust in the tank so I didn’t attempt to coat the entire tank, just the bottom third. I sucked out the excess sealer with a turkey baster and kept rolling the tank until the sealer stopped puddling. So far so good - no more leak. The pics are before and after. 2006 Ducati 1000DS Super Sport
