Seam Sealing Epic Material ??

you’d use mcnett, the silicone, not urethane, seam tape & urethane won’t stick to the silicone of the epic or silnylon.

just curious on that note, would anybody out there pay for seam sealing services?, i’ve gotten pretty good at it & wouldn’t mind seam sealing others gear for a small fee.

I’ve had good luck sealing Epic and Silnylon with both clear GE silicone II caulk thinned with lacquer thinner, and also a Dow Corning product used for sealing circuitry (some electronics shops carry it) called DC-3140. The DC-3140 doesn’t have that vinegar smell as it cures.

I prefer lacquer thinner to mineral spirits as the solvent smell dissipates faster. I generally use 1 part silicone to 2 parts thinner. It takes a bit of mixing to make it homogenous. This is a thin mix that penetrates thread holes well and wicks into thread, though you can’t see it running through.

Sometimes after a leak test fails a second coat is needed, but not often. I apply with a syringe and then use a brush to spread it if necessary. Seam sealing is a PITA but worth it.

Thanks for the replys :O)
