I'd like to ask about the body fabrication......... 1)Did you use Casting Plaster (I believe this is plaster of Paris)?
2)I've done some googling, but can't find an answer... Is the CP liable to crack if it's too thin (or indeed too thick)?
I'm thinking that using Celotex foam covered with a thin layer of CP could be a good way to make a buck to take moulds off (I understand it would have to dry about 3 weeks and then be coated with shellac or poly varnish to seal, and then waxed to take moulds off)
3) Did it take many, many hours to achieve the good finish you've got using GRP over the casting plaster - did you have to fill/flat much? - I can see the appeal of the method for a one-off because it avoids the cost of moulds
