tank sealer peeling off


Recommended Posts


I have a fibreglass motorcycle tank that I aquacleaned and then treated with tank sealer.It started to leak again and the sealer has crinkled up and can just be peeled off. I now realise that I should of rustblasted first, but would this account for the sealer crinkling up - it looks like it has reacted with the fuel?

how do I clean out the sealer without damaging the fibreglass tank?

thanks Mike

PEELING (Flaking, Delamination)
A loss of adhesion or separation of the paint film from the tank surface.

Improper preparation of the substrate (cleaning & etching).
Inadequate drying of tank interior prior to applying sealer.
Too hot/humid atmospheric and/or tank surface conditions during application or curing.

Strip out Tank Sealer (Using KBS Strip). Repeat AquaKlean, RustBlast, and Gold Standard Tank Sealer steps.

Thoroughly clean and prepare all tank surfaces according to product recommendations.
Allow tank interior to dry completely before applying sealer.
Allow tank to reach normal room temperature before applying sealer.
Allow tank to dry slowly at room temperature.
Do not attempt to "speed up" the cure time by placing tank in direct sun or near heat source.

Yes, the sealer will crinkle if it never has a chance to fully cure because the surface was not etched with the RustBlast.
