Make sure your fuselage doesn't leak by ordering a quart-size kit of 3M™ Aerospace AC-350 B-1/2 Fuel Tank and Fuselage Sealant from SkyGeek. The fuel tank sealant is designed to be resistant to aircraft fuels and aviation gasolines, filling in gaps and cracks for a secure, reliable seal. The specialized sealant is dark gray in color and is a class B-1/2, Type II Spec formula. The 3M fuel tank sealant is designed to be mixed just prior to use, then goes on smoothly and cures readily for a long-lasting seal you can count on.

*Application Life refers to the length of time that mixed compound remains at a consistency suitable for application with roller or brush. Application life is always measured at a standard temperature of 75 degrees F with a relative humidity level of 50%. In general, for every 20 degrees F rise in temperature, the application life is halved; and for every 20 degree drop, it is doubled. High humidity levels during the mixing process will shorten application life.
**Tack-free Time is the length of time after which a mixed sealant will no longer tightly adhere to L-LP-690 standard low density polyethylene film.
***Cure time is defined as the length of time it takes AC-236 Class B sealant to reach 30A hardness. It depends on three factors: remaining application life, temperature and relative humidity. To a certain extent, the temperature/humidity factors for application life also apply to curing. To accelerate the curing process, apply heat up to (but not more than) 120 degrees F.
