Hi Chris,
The spec for pro-seal is MIL-S-8802 Type II B1/2 or B2 or A1/2 or A2. The "B" means you apply it with a spatula or tongue depresser, its real thick like peanut butter. The 1/2 means .5 hour pot life, 2 means 2 hour pot life. The "A" means its a thinner mixture like thick paint. I would use the "B" for fuel panel sealant. The "A" is usually used between skins on pressurized acft. It should be mixed 10/1 by weight or volume. If you don't have scales mix it to a dark grey but not black. Putting extra hardner in will make it cure a faster but it makes the sealant weaker. It is strong stuff, it has a shear strength of around 300 pounds per square inch. I hope this helps.
Good Luck,
Swaid Rahn

Folks,
I put an inspection hatch into the inner wing rib to allow access into the
tank. There's a large phenolic ring embedded in the inner side of the rib.
I'm now looking for some gasket material to replace the 40+ year old
rubberized cork material I used for the trial assembly while building. The
photos show the hole with and without the aluminum cover plate. I'm
requesting any suggestions for gasket material and any additional sealant
needed. Thanks in advance.
Regards, Chris.
