With the great thread on RTV Silicone molds, I decided to try to go that route and make my first mold. I have a question.
"RTV Silicone" is different than "100% Silicone" The title says RTV but the posts seem to say just plain old 100% silicone. I bought a tube of "High temperature" RTV at an auto parts store and the stuff was nasty. Very strong fumes, hard to work as its very stiff. I ended up making my mold box too large for a tube so I failed my first attempt.
Then I read some stuff about RTV molds and it seems that people are using 100% silicone and adding water to basically turn it into RTV? I actually went to walmart and bought 4 more tubes of RTV. These were "low odor formula" regular "blue RTV" They were $4 each for small tubes. I was looking at plain silicone and it is much less expensive.
Am I using the wrong stuff? Can I use the RTV now that I have it? IS there any way to thin it out a bit so it flows better?
Thanks

My name is mike. Long time lurker etc. I love plastics and bass fishing as well as art, design and sculpting. I want to get into pouring and eventually make my own original designed baits. I have been researching, sculpting, messing with POP molds and buying materials for a few months and decided that the winter would be a good time to start actually pouring.
thanks again
