Hi Andy,

A post-cure in the mould would be a very good thing to do to ensure that there is no danger of the part distorting. 60'C for 6hrs would be a good post cure, after that there should be no danger of the part distorting in the sun.

If you need to post cure out of the mould then the recommendation would be to increase the temperature very gradually over  along period of time. This will reduce the amount of out of mould distortion.

All the best, Matt

Another idea if your parts are too big for an oven is a modern temperature regulated heat blanket. I used one when I first made a bonnet at home and it achieved a mould surface temperature of 40 Celcius when placed on the complete infused mould layup, then wrapped in a duvet to reduce heat loss.

Although modern electric blankets have a thermal cut out and are designed to be left unsupervised, I would always recommend keeping a close eye on it as it isnt being used as the manufacturer intended.
