This part is quite small 39cm x 9cm. ive made two using just epoxy infusion and one with GC50 and infusion. The GC50 released with no problem at all, but the two straight infusions left resin from the surface of the part, in the mould. once infused i put it in an oven at 55c for 12 hours. i also put the pot that had the left over resin in the oven as an indicator. the pot and surface of the vacuum was solid. once started to release the part i heard a slight crack which i recognized from the first attempt. on the second attempt i put 6 easy lease coatings on the mould as did not want it to happen again. any ideas? Many thanks Mark Attachments IMAG0998.jpg (389 views, 897.00 KB) IMAG0997.jpg (352 views, 774.00 KB) IMAG0999.jpg (350 views, 1.00 MB)

They reckoned as i was putting the infusion into the oven at around 50c, their was still styren in the uni mold. they said to try the infusion and cure at room temp 20c. well i was excited to see if it worked, and thankfully it did. once cured i post cured the piece in the oven and all was fine. what a big relief. Thanks guys Cheers
