might need to take a brave pill before attempting that

Back in my kit car days you used to see a lot of probs like this with moulds. Usually where they had spent the time to make up a proper jig/frame to support and brace the mould, so hen after turning out a few tubs/panel the mould would distort.
You then got nice (non intended) shapes in the moulding
