If you heated the interior of the hull to 20 degrees then got the area around it to a similar temp with the heat lights would that prevent outgassing.
Jeff,
Outgassing is caused by the temp of the timber increasing after the resin is applied. The air inside expands and the extra volume of the expanded air tries to escape.
You can get outgassing just by the day getting warmer if this translates to the temp inside the workshop and hence your timber also increasing in temp.
When I want really good penetration of resin into timber I will deliberately heat the timber and apply the resin and then remove the heat source. Then the opposite to outgassing occurrs. The air in the timber contracts and draws the resin in.
If I was going to do a big laminate job over timber I would wait until the hottest part of the day where I knew the temp would not increase further but fall and then do it. Just a small precaution I would be working on timber whose temp is falling or going to fall. Probably something more applicable to building a cedar strip craft in an outside shelter where the temp can change quite a bit during the course of the day.
I am quite fortunate these days because the temp in my workshop varies very little no matter what happens outside.
