I've read that many of the sealers can be removed using a stripper or MEKP. Does this apply to the KBS kit also? If not is there a solvent that would be recommended?

Thanks

You will want to use the KBS Strip to remove the Gold Standard Tank Sealer.

You can find KBS Strip here: http://www.kbs-coatings.com/kbs-strip.html

Use KBS Strip (or a paint stripper containing Methylene chloride) for the most effective removal of an old failed coating. Pour some KBS Strip into tank and carefully rotate tank to allow contact with all sides. It may take multiple applications of KBS Strip to finish the job completely. Old Sealer may come loose in big chunks or small pieces so use a long tweezers-type tool to help remove it from the tank. After stripping is complete, rinse tank generously with water and proceed with the KBS 3-Step System for Fuel Tank Preparation & Sealing. (NOTE: When stripping a Fiberglass Tank, surface contact with the stripping agent should be kept to a minimum to avoid the attack & weakening of the fiberglass resin.)
