thank you verry verry much for your help!
btw what kind of paint do you appley to the rtv mold as base coat for the foam lure? (acrylic ?)...
do you have the "original" tutorial with pic's?
No, but the instructions are pretty straight forward. The Silicone Caulking will only hold so much water so you can't make it too thin.
Any spray paint. I use rattle cans from Walmart. Technically, the foam is sticking to the paint so the adhesion is remarkable.
BTW, the method I describe to stretch out the Silicone and make it more affordable may
require you to cover your model more than once if you're not totally covering it. You want the "Good Stuff" to encapsulate the lure, totally. The thinnest of coating will suffice.
Another thing you can do is make "Filler" pieces, pebble sized from the cheaper silicone and put them in the mold box after you make your initial coat and it cures. Put some good stuff in so the pebbles will have something to grab on to, add the "pebbles", and then use the good stuff to cement it all together. You may only use an ounce where you would have used 4. Once it sets up, it'll be a pure silicone block.
Try a test piece to assure compatibility. Usually, the cheaper stuff will stick well to anything so I'd be more concerned with the Molding Silicone if you're going to use the filler method. Good Luck.
