Does any one know if the delmart rtv is clear?  I'm going to make some swimbaits like the moneyminnow, will i need anything other than the plasticsol and some color? thanks!

I'm pretty sure it is blue, with a white reactive agent, making it a finished color of powder blue. Most are like this. if you are looking for clear, you might want to try a resin type material but you may be limited to the heat it can tolerate. Nothing wrong with the blue... I make a ton of molds myself for my hand pouring business and for sale.

The reason I wanted clear was to be able to pour it around a bait and then be able to accurately cut it down the middle to make a 2 piece mold, when using the blue how to you do a 2 piece one?thanks!

I don't think that is the easy way to do it. You have to be spot on with the cut and I don't think I could even be close. 2 ways to do it with RTV.

1- Make your frame and fill it half way with your RTV mix. Let it start to harden. Figure out how deep you need to set your master (forgive me for saying) bait taking the setting RTV into consideration. You need to make sure the bait is literally suspended halfway into the RTV. Let it harden. Next, you need a release agent sold where you buy your RTV...micromark is a good shop. Slather the top of the finished mold with the release agent and then pour another batch of RTV on top of it to make the 2nd half. It'll work. They will separate when hard.

2- make a clay copy of the bait. Cut the copy in half. pour a bottom covering layer of hot soft plastic into a frame. as it is geling up, place the half clay copy in the frame. Pour in RTV. Next on both the top and bottom of the RTV as it sets, place an alignment peg. Once you can take the mold out, simply repeat the process and after your second half is ready, match up the peg holes and you should be in business.
