P/S Class B is an aircraft integral fuel tank sealant. It as service temperature range from 65┬░F (-54┬░C) to 250┬░F (121┬░C), with intermittent excursions up to 275┬░F (135┬░C). This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.
P/S 890 Class B is a two-part, manganese dioxide cured polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.

The Frekote 770-NC synthetic mold release I ordered has a 6-month shelf life from the factory. The can I received on 8/25 was set to expire on 8/31 according to the date printed on the bottom of the can. I called and sent a photo of the can bottom and they said it should have been taken off the shelf a month earlier, so they will send me a good can when new stock arrives without sending the out of date can back.
I appreciate the fast delivery and them taking care of the issue, but it means you could be buying product that has only one month of shelf life remaining. Call before you buy and have them confirm the expiration date of their stock and if it is less than works for you, work out delivery from fresh stock or negotiate a discount.
It's the standard pilot log for a reason. Many different flight time categories with just enough space for remarks. As a helicopter pilot, it would be nice if the endorsements section wasn't fixed-wing focused; but I get that there are a lot fewer helicopter pilots out there, so I won't dock any stars for that. This is my third ASA-SP-57 logbook at this point, and I intend to keep getting more of them in the future.
