Hi guys...I want to transition to prepreg and I'm trying to my head around some things before I invest...I'm not 100% sure prepreg will work in my very complex multi part mold so minimizing investment until I've got some confidence would be good.
...Big question is will I be able to get a decent indication of potential using XC110 in an oven that wanders either idea of setpoint by about 5 degrees?
...Another challenge is that the layup includes an already formed dry carbon panel on one of the mold parts, will the XC110 have enough resin to adhhere to that panel?

Lester is correct about the adhesive film.  Something like our XA120 would work well in most cases. 

In terms of oven temperature variation, its hard to say for sure. A few degrees here or there and you should be fine.  Significant variation for a significant period of time may well effect the resin flow characteristics thus impacting the cosmetic finish quality.
