Hi,k I have been skinning interior parts with 3k twill cloth, and have noticed in this cold weather it's taking a lot longer to cure. So I have put these parts beside my water heater. I am wondering what are the ideal conditions for curing and if say a plug in heater would help speed the cure.also, would a dremel be best to trim the edges off then sand? 

Epoxy needs to cure at around 20 degreesfor its full cure cycle. Anything less and it can ‘go off the boil’ and end upnever going off properly. As the weather get colder we get many calls frompeople with problems with resin curing, in most cases it's because the workingenvironment is colder that they thought.

Excess humidity and cold combined can be a killer for epoxy curing meaning it sometimes won't cure at all!  To rectify that it will need curing well above 20c in a dry environment to drive out the moisture.  Even then it might need a recoat to get rid of a tacky surface.
