flexible and keep them from cracking?
OK, everybody now!—303 Protectant
Monthly year round
if you’re serious about preserving your gaskets
303? Not KY Jelly or Lithium grease?
Sometimes getting the blasted things off, I wished I had used KY or vaseline.
I don’t have a drysuit, but have used this stuff on hatch cover seals on my QCC. It dosn’t offer any UV protection (that I know of), but it sure keeps rubber/latex type O-ring seals in great condition. It is not cheap, but I thought I’d throw it out for consideration. It is pretty safe stuff also (dupont makes a food grade), but look up the MSDS (probably should wash it off your fingers if you are a smoker).
…avoid getting sunscreen and anything oily on them. Even at that, if you use your dry suit a lot, the seals will probably be shot after three seasons. Fortunately, they’re easy and relatively cheap to replace.
303 protectorant every month
