If I have a previous coating in my tank, should I remove it first before sealing up the tank with your tank sealing system?

Tank Sealer is formulated and designed to stick to a bare surface that has been prepped with KBS Klean (cleaner) and RustBlast (acid etch). With that in mind, it is always a good idea to strip out a previous sealer with KBS Strip before starting fresh.

Directions for Stripping Out an Old Tank Liner

  1. Pour some KBS Strip into the tank and carefully rotate it to allow contact with all sides. It may take multiple applications to finish the job completely.
  2. Old sealer may come loose in big chunks or small pieces — use a long tweezers-type tool to help remove it from the tank.
  3. After stripping is complete, rinse the tank generously with water.
  4. Proceed with the KBS 3-Step Tank Sealer System for fuel tank preparation and sealing.

Note on Fiberglass Tanks

When stripping a fiberglass tank, keep surface contact with the stripping agent to a minimum to avoid attacking and weakening the fiberglass resin.
