Or just closed mdf box? Im in the process of moving to prepreg as i have found awesomely cheap ooa prepreg here in turkey which they claim the results are pinholefree in oven only prepregs. May be i can getaway without getting an autoclave. (Altho i have quote for autoclave £500 yes 5 hundred quid without the heating elements, its a 500 litre and will be made from 8mm thick steel) so how big is ur oven? How long does it takes to get the relevant temp? Sorry for loads of question :-) Regards
