Fiberglass repair materials difference?

Is there a difference between the material used in “emergency” and “regular” repair kit?

I’ve seen one (repair) done in the field and it “cured” (at least that’s what the box said) in 20 min. Is that strong enough? If so, can I just use that for home repair?

If not, how do I tell one from the other and find the right one(s)?

And last, but not least, where can I find them? What are the brand name to look for (or avoid)?

i have a quick cure
patch that will fix the injury during a trip-but these types of fixes might not be the most pretty…you clean it up when you get home and have a dry shop to work in to make it nice nice…

West Epoxy with 205 hardener is what
I use. Some of the field repair kits are made by West. Unlike vinylester (which I have also used), West epoxy will keep good in the cans, with the metering pumps still mounted, for at least 3 or 4 years. Vinylester and polyester will set up much sooner, because these resins come with a tiny amount of promoter mixed in. West epoxy will stick to polyester or vinylester boats.


For emergencies. Maybe this is what corgima referred to? The advantage is it works when wet. I saw an on water repair of a huge thru-hull gash in a Romany. The inside of the kayak stayed completely dry for about 6 hours afterwards, and I was told the stuff would stay in place long term if you didn’t mind the way it looked. It’s supposed to be much easier to remove than Denzo tape and a 5’ strip costs around $20.

Resin and cloth for the long term repairs (surface must be dry) like the others said. But resin has a short shelf life, so unless you’re a regular in rock gardens or surf, it might be cheaper to just carry stuff for the rare emergency and buy the resin for the occasional repair.


Better prices here:

Much better, thanks!! NM
