Hi Shas, thanks for the great advice. I've had the 2am wake-up session about exactly that. I've sealed some pine a while ago with a water bases sealant and it rotted......What I'll do. When I see the rot settling in, I'll give the inner liner another coat of glass and let the wood fade away. It is treated shutter board, so hopely it will be a while.
Hi Foodchain, Thanks, you have a good point. I'll give it a go with the next mould. It seemed tidier to contain all the resin inside the mould.
