Best way to check if Poly Resin is still good.
Seems there is some different opinions on Poly Resin in regards to shelf life, temperature extremes, etc. I still have 5 gallons of unopened general purpose laminating poly resin. I have keep it stored in the utility room adjoining the garage with the electric water heater. I am relatively positive it has not been over 90 degrees or under 35 degrees in that utility room. The container shows a date of 05/14, so all indications are that it was packaged in May of 2014. Every week or two, I have shook the pail, rolled it around, etc. to keep it mixed. I turn it over and let it sit till the next time I shake it etc.
My questions are: What is the best way to know if it is still a viable product to be used on the boat? If I mix a quart at 1.5% to 2.0% MEKP, apply it to a scrap piece of plywood, give it time to saturate and then lay down a piece of 1708 or CSM saturated with the resin, what should I look for to verify it is giving a good bond etc. Losing the 5 gallons isn't acceptable, but at the same time using it and having problems 6 months later is even less acceptable :blue: .
I would like to hear from I-Boaters that have actual experience with this situation please. As always, I appreciate all information. Ondarvr, where are you?
