The infusion resin I now plan on using has a 2-hour pot life at 77 degrees F (basically room temperature). No gel time/working time is listed. I have contacted the manufacturer to try and get this information. I imagine it is close to 8-10 hours. Why is elevating the curing temperature a bad thing? I would love to boost the temp to a minimum of 100 F after the infusion has completed.

Thanks...Alan

higher temperature during the initial cure can "cook" the resin similar to what happens in the mixing pot after a while.
Not so extream but can effect the final strength

Thank you for your reply. Not sure if this is relevant, but I have changed my plans some and will only do a single layer of 9 oz. s-2 glass on the inner and outer layers (plus core). Could I boost the temp say 5 degrees every 2 hours? I plan to start with the resin and hull temp at approx. 
85 degrees. The resin I am using has also changed. It's PTM&W MVS-610/620. Pot life at 77 degrees is 2 hours.
