rhahn427 Posted April 17, 2009 Report Share Posted April 17, 2009 Which is better for making molds, urethane or silicone RTV? Also is there a use for each? urethane RTV seems to be about 1/2 the price of silicone. Quote Link to comment Share on other sites More sharing options...
longhorn Posted April 17, 2009 Report Share Posted April 17, 2009 Please explain more about what urethane and method you're talking about. I don't recall ever hearing about a urethane mold. I'm always open to new ideas though...have a great weekend. Quote Link to comment Share on other sites More sharing options...
