Is Cycloaliphatic Epoxy Really Moisture Insensitive?

[HVAC Cruiser]

Well its supposed to rain here today and I want to get my fiberglassing done.
The boat is under cover in one of those big tents but the humidity here is 92%

I am using AeroMarine Cycloaliphatic non blushing epoxy #300/21 it states that it is moisture insensitive and usable in damp conditions and high humidity. Everything to be glassed is dry, should I believe them or will it raining weaken or have adverse effects on the work?

any thoughts?

Damp conditions and high humidity aren't the same as rain... if there's a chance that water will actually drip on the epoxy, wait until it's not raining and not going to rain during most of the cure.

Moisture insensitive epoxy is great, but it's not really meant to harden underwater.

Thanks for the info Erik

The boat is under a shelter, rain can't drip on it so I guess i'm ok I hope lol. I actually just came in from tabbing the transom and the wood I replaced yesterday.

Tell you what though, this is the 1st time using this brand and I love it, its only 600cps viscosity man does it wet out great
