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.

I work on old vintage motorcycles, most of which have a fair amount of oil and grease on the engine and transmission parts. These gloves are so much better than the run of the mill cheapo's that can be bought about the same price. Yes, these will tear like any nitrile glove, but these are very, very durable and do a very nice job of standing up to gas, oils, and brake cleaner. I've yet to find any better than these for the price. No complaints whatsoever.
I took the chance of ordering expired Loctite 330. It was jelled up pretty good and generally unusable. It was my fault for trying it and never called the company to complain as I took the chance and that is on me. Order the good stuff.
Had used aviation Camguard for years. Added as well to each quart of oil added to my Lyc 540 SIA5 aerostar engines. Went past TBO with excellent compressions. Oil analysis always normal.
Also add to automobiles but too early to see a benefit.
