Per Grip:
Should be OK Pete. I'm sure you already know of the 303 stuff. If you do not
see any signs of dry rot ( tiny cracks appear when you stretch it ), I would
not worry much. I kept gaskets going for 5+years by applying it at regular
intervals.

Thanks.

Yeah - I slather my dry suit seals with the stuff after every use.


Something that I've learned, though: beware of 303's large spray bottle. It's
brittle to the point of being ridiculous. Drop it and you've lost the contents
and have a mess to clean up.

Been there.... *twice* already....!!! Slow learner, I guess.... -)

Now, whenever I buy the stuff, I decant it into a more durable container and
fill a little spritz bottle with some as needed.
