Steve,
You have a problen with the tubes in that you are stuck (no pun intended
) with the filler that is there and no chance to use cloth.

Stop by BoatWest and look up 382036 with is a six-pack of little
packages. Throw that in a box with pill bottles (labeled) of fillers
and a sandwich bag of assorted cloth patches. Add some clean yogurt
cups, stir sticks and at least three gloves.

You are ready for anything that can be repaired underway.

I've used them myself around the shop, rather than mess with the pumps, etc.
for simple jobs.

I'm putting together a fiberglass repair kit to keep on the boat while
cruising. Just for the small crack or ding or broken widget.

Not sure how good this stuff really is, compared to West System,etc.

Can I mix it with the fillers, etc.?, will it bond to polyester lay-up for
small hull repairs. I have boxes and bags of scrap cloth, etc. and more
fillers than I will ever use.

The biggest advantage, I see, is convenience and cost. ACE Hardware has
store brand for a couple bucks a tube.

I have also noticed that these tubes seem to survive for several years, even
after they have been opened. I use one the other day that was at least 5-6
years old and it still kicked over.

Thoughts??
