[NHCOLL-L:5623] Re: Gaskets for wet collection vats

[malcolm McCallum]

Unsure if it will work, but if you go to an auto parts store (Autozone for
example) they sell stuff you use for sealing your head gasket in the car.  I
suspect the same product would work on your vats, just apply it like
squeezing a toothpaste tube, lay the bead where you want it, let it cure,
viola!
