thank you kindly for the info!
unfortunately I have yet to see the keel myself as the boat is still in the water. this is second hand info, although i have no reason to discredit it.
Will temperature really have that great an effect? And I've heard Talc has moisture retention properties, any truth to this?
After sandblasting is one priming coat of epoxy sufficient on the keel, and then i can move onto filling?
I finished mine off with 3 coats of epoxy resin and 3 coats of Interprotect (there was still discussion as to the best sealer at that time). Now I'd just use Interprotect for all coats.
How much dry time is necessary between coats in your experience?
