IG Heads

Poured RTV for IG heads and arms but it hadn’t set overnight. I think I’ve been a bit heavy handed with the blue compound in the past because I’ve got plenty of rubber left but not a great deal of catalyst. Will give the molds another 8 hours to set today while I’m at work and then pull them out (set) or clean off the masters. In my experience if the RTV hasn’t set in 16 hours it isn’t going to set at all.
