The Gold Standard Tank Sealer will work. Just follow the directions found on this page for Fiberglass Tanks: http://www.kbs-coatings.com/Gold-Standard-Tank-Sealer-Information-Instructions_ep_39-1.html


The procedure for sealing a Fiberglass Tank is the same except for a variance in Step #2 - RustBlast. For this type of tank, thoroughly wet the fiberglass surface for only 2 minutes using RustBlast. Drain and rinse well with water as directed. Because you are not prepping metal or dissolving rust, RustBlast may be saved and re-used for future use. RustBlast will, however, treat the fiberglass surface by giving it a more acidic pH level & by leaving a zinc phosphate coating ideal for Sealer adhesion.


Also, it is important to make sure that the tank is completely dry inside before sealing. Drying is best accomplished by introducing forced air into the tank by using a shop vac, blow dryer, or fan. (NOTE: Drying is a critical step for sealing fiberglass tanks. Fiberglass tends to hold moisture and if the tank is not dried completely, the Sealer will not adhere properly.)


IMPORTANT: It is also very critical to methodically coat the entire fiberglass tank completely & thoroughly with the Sealer. If any part of the fiberglass surface should accidentally be left exposed or unsealed, however, these unprotected areas will be very susceptible to deterioration by alcohol blended fuels and it is therefore highly recommended that these fuels not be used in fiberglass tanks even after sealing. After coating the tank, remember to drain well to avoid pooling and puddles.
