I have just encountered a problem that I am sure has been answered many times before but somehow a search in the forum brings back nothing. oops Apple iMac posted only part of the question. I have just produced a small curvy part and have a fairly bad case of insufficient resin penetration. The Vacuum was perfect, held for 12 hours before infusion and perfect afterwards. My suspicion is that the IN2 resin was not warm enough, it was below 20C and I used an electric blanket after infusion to bring the temperature up. I noticed on infusion a lot of de-gassing going on which settled after about an hour. Is it possible the resin was too viscous for the gas to be extracted fully and therefore prevent full resin take up. On the course we de-gassed and this gave a marvellous result. If a higher temperature can be achieved i.e. warming mould and resin up first what would be a good temperature to ensure a better penetration. I don't really want to have to buy a de-gassing setup if it can be avoided.

Thank you both for your very quick responses. Just to say also to Mark, I did have a resin break of a good inch and I let the resin run through to a short way up the exit tube. The actual infusion took about 20 mins over 6 inches and by the time the front arrived at the break the cloth appeared to all be infused. is it possible by leaving the vacuum on test for leaks over night that I had compressed the cloth too much. Also I think Paul said on the course that leaving the infusion mesh out is OK on small parts. I will try again with a warmed resin. De-gassing noted. Thanks for your help.
