Cycle Tank Sealer Kit Overview

The KBS Cycle Tank Sealer Kit contains everything you need to seal a tank of up to 5 gallons.

Gold Standard Fuel Tank Sealer, from the makers of KBS Coatings, is a superior, single-component, ready-to-use fuel tank sealer.

Gas Tank Sealer

Gold Standard Fuel Tank Sealer is specifically formulated to stop rust and corrosion by forming a tough, fuel impervious coating while simultaneously sealing small pinholes and weld seams.

This kit contains our KBS KBS Klean (a water-based, heavy-duty, cleaner/degreaser) and KBS RustBlast (a powerful rust remover/metal etch) to obtain a permanently sealed, rust-free fuel tank. These KBS prep products are formulated with a unique Oxygen-Block Technology which reduces the occurrence of flash rust by over 80% and extends rust-free storage times by leaving a temporary protective coating in addition to a zinc phosphate film.

Q: I want to order the basic cycle tank repair/sealer kit, but i'm being asked if I want the Mesh too. What's the mesh for ?

Asked by:  - 10/7/2013

A: The Fiberglass Mesh can be used to seal up and reinforce a weak area or an area with several pin holes. This is done on the outside of the tank with some of the Tank Sealer used as the "resin" for the Mesh.

Rating Best product to seal your tank
I used this to restore a fuel tank on a 41 year old snow thrower. Due to age and harsh conditions, the tank had begun to scale and continually clog the carb with rust particles. Not any more! And it runs as good today as it did when my dad bought it in 1969. I have two classic motorcycles I plan to use the KBS system on in the near future.

Rating Exactly What it Claims to be!!
I used the KBS product for restoring a heavily rusted small motorcycle gas tank. You have to carefully follow the instructions and take your time through each process, but the result is perfection. I recommend you take a day for the Aqua Kleen and Rust Blast processes, and a second day to do the sealant coating. This process takes a long time but it completely cleaned out a very heavily rusted gas tank and sealed it. The result was amazing! I highly recommend this product. It is safe on your painted or decaled surfaces if any of it dribbles over. It didn't harm the outer surface, but be sure you immediately wipe up any unwanted drops of the sealant or it stays on forever. Watch the online video, thoroughly read the instructions, and take your time, and you will be happy with the results.

Rating Great product for aged/rusted gas tanks.
Good product to coat and seal gas tanks. The product is exactly as it is described. I followed the directions to the letter and The results look great. I used the motorcycle kit. The tank had light rust on the inside bottom and a bit heavier on the inside top. The prep stages did leave a slight rust film in areas, not bad though. Time will tell if it holds up as it is intended. Thanks KBS.

Rating Simple, effective product
Great product that gets the job done when it comes to coating the inside of a gas tank. Used Kreemed before and it peeled off all over the place, clogged up my carbs. KBS coating worked amazing on my old gas tank and got me back on the road again - which is what I wanted! Great product, goIng to buy another kit for my other gas tank. I am not a KBS employee or frequent reviewer (in fact I dislike doing reviews) but it worked so well I thought I would comment. - Kile 1982 Kawasaki kz1100-A2 running strong at almost 30,000 miles

Rating Motorcycle tank inside looks factory new
I coat all bolts, eg. petcock bolts w/ grease than install. grease keeps product from sticking 2 threads. Petcock holes need more than tape. I use custom made 1/8 flat stock steel and rubber, bolting to bottom of tank using grease coated petcock bolts to close hole during coating process.

Rating Best Tank Sealer on the Market
The KBS tank sealer addresses all of the issues that are common to refurbishing a gas tank. Rust removal, neutralizing the base metal, and complete surface coverage with a rock hard sealer, that is impervious to fuels. After 37 years in the motorcyle industry, I appreciate having a product that really provides a dependable solution for tank repair.

Used kbs to clean a gas tank on recently purchased bike. The bike definitely sat out in the sun, causing extreme rust in the tank. The simple steps cleaned the tank and gave a like new feeling to the bike
