hiya - very new to prop making
I am mostly interested in helmets and have been readin some info on using FG
I think I have the general idea is :
FG matt + resin
I tried some a few days ago - just to see wot I could do/use
just trying materials.
Just using a random mold, I used release agent, gelcoat, layered FG + brushing in resin.
result was - out side was nice and smooth - inside however; wasnt as smooth, had a few strands of the matt FG poking out - rough to touch and irritant to skin as well.
(1) is my rough interior just a matter of bad technique?
(2) how to solve rough FG interiors - a mate suggested gel coating the inside too! Or bondo and sand? Or sand FG directly? Some use rota cast polyurethane resin (wot is this stuff even? any got piccies or links pls)
(3) was follwoing DangerRuss WIP - he uses "shell shock" from smooth on and re-enforces with FG. I understand shell shock is a brushable plastic; when used this way - does it therefore substitute for the gel coating on the outside?
Thanks for lookin at questions!
