3M 5200 cure time

[NHGuy]

I used some Fast Cure 5200 yesterday for my transponder mount holes. The holes had been drilled too low by my boats previous owner. So I drilled oversize new holes about double the size needed, redrilled the bad holes to the same diameter, and filled all 4 with the 5200.
The temperature went down into the 30's here overnight, it is now lower 40's. I just went out to check my boat and found the 5200 feels rubbery. Does this stuff harden fully or does it stay pliable? I don't know if I want to put transponder screws into stuff that is this bouncy.

5200 does not harden like Marine Tex or epoxy. It is a sealant/adhesive. The way to use is for mounting a transducer is to drill the correct size holes, coat the threads and holes with 5200, and screw it in. The 5200 seals up the holes do water doesn't leak in.
