New technique a bit like skinning?

The idea goes something like this: Cover the part in release agent then single sided prepreg, epoxy side out and secure edges with tape or temporary glue Cover the prepreg tightly (no air bubbles) with thin clear flexible heat resistant gloss sheet gloss side in; e.g. silicone or latex Seal the sheet behind, either to itself or a backing with vacuum connection Cure it in an oven Remove the laminate from the original Add extra layers inside the first and cure using whatever technique you fancy Gotchas: The part has to be good for 100ish degrees Would the epoxy stick to the silicone and does anyone know if latex would work? BTW really excellent Easy Composites videos, infusion is so impressive. Rich

The difficulty will be preventing creases one the outside where you have put your vinyl or whatever you use. Tight corners etc will probably end up pleating leaving an imprint. I use a similar method for making kart floors. As there is such a huge range in shapes and sizes, it is not plausible to have moulds for them all, so I infuse off the back of an aluminium one
