RE: Polyester Resin mold for epoxy resin fuse?
Everyone thank you very much, IlÂ´ll be trying once again with polyester resin.
I have done some other hydrocal molds for Q500 fuselages using a High Gloss epoxy resing with very good results and without having pieces stucked.
I think maybe as commented by speedracerntrixie polyester resin was not entirely stiff yet, IÂ´ll try again leaving more time for polyester resin tu entirely cure and as you mention with better wax and PVA
Thats the advantage of hydocal molds,,,,,,,,practically if something goes wrong you can just do it again and with very little cost added but of course I would rather have it correctly done next time.....Im not willing to be pouring hydrocal all the winter.
One thing I did different this time is that the original pink foam fuselage from where i made the molds, I seal it with epoxy resin so it was very stiff and gets out perfectly from the hydrocal molds without a scratch and they are ready in case another set of molds are needed, which is the case.
Thanks for your help,
