Some of you might remember this test of 10+ year old 2 part flotation foam? I originally posted this video 2 years ago. I can tell you that while it might have been fine after 10-12 years on the shelf unopened, when I opened it today to actually start pouring some foam into Whisker Seeker two years later it was no longer a liquid. One can was basically a solid. I wedged a lot of the original foam blocks into the boat, planning to add some new foam to cement them in place and increase the flotation a little. I was in the boat with mixing cups and a can for mixing. FAIL. I guess I’ll be ordering NEW 2 part pourable flotation foam shortly.
It might have lasted 10 plus years sealed, but it didn’t last another two after was been opened. Yes, I had sealed then down tight with pliers too. Oh well.
