Just did what is probably the scariest thing I have done in this hobby .. flattened a set of 47 year old plastics in the oven .. doubt I would find a set if I buggered it up . Luckily they turned out really well . I forgot to take a before shot but they were pretty bad.
4 mins at 110 degrees in a fan forced oven .
This was my 1st attempt at flattening plastics too .
