How did you prepare the plug surface? Sanding till 1000-1500 and polishing afterwards? The smoother the surface, the better. If your surface was shiny, and the filler didn't shine through, there has to be something wrong with the application of the release agent. Polyester usually cures quite good without elevated temperatures.

How many applications? it was the uni mold kit ' not very old easy lease and about 7 to 8 coats of the plug and moulds ' I'm not blaming the kit it was probably me doing something wrong I didn't cure the plug in the oven would this have caused it ?

If he makes the mould using Unimould then his best bet when curing the pre-preg is to follow the low temp cure cycle followed by a free-standing post cure of the carbon fibre pipe to achieve maximum service temperature. Yeah, being stupid again!
