Mould Restoration - refinishing & sealing

Hi all,

First post on the forum.

I've recently acquired some Composite moulds from a motorsport manufacturer. They are mainly airboxes and intakes - GT2, GT4 cars.

Having had a long held interest in composites I've decided to use this as a rather large stepping stone. I've done some repair work previously during a past life as an aircraft engineer, although these will be my first 'proper' Carbon fibre projects. I do intend to try smaller projects first prior to jumping into these.

So, my question is, the moulds have been stored for a number of years, what would be the best way to bring them back to life? They are all in pretty good physical condition, with no scratches or marks on the mould surface, although they definately need cleaning off and I'd imagine that re-sealing them wouldn't hurt.

Very interested to hear of any reccomendations.

Thanks, 

Michael.

You could infuse that quite easily, but I think it will make a mess of the moulds if you dont have the experience to control the resin bleed. Pre-preg will give you better results and the moulds will last longer.

Fun mould to play around with though!
