    I have made my first mold of a fish. I used a 22 inch quilback carp sucker I shot last year bowfishing to "test the waters" with. I used the 50/50 Bondo and resin method and then layered it with fiberglass. I touched up the few air pockets and imperfections with apoxie sculpt. Now I need to find gel coat. Where can I get gel coat and pva? If I use mothers carnuba wax on the mold do I still need to spray a layer or 2 of pva on the mold?
     
  2. I think I used to get it from WASCO, McKenzie now. I'm not sure if any of the others carry it or not. I can't answer your question about the carnuba wax, but I can tell you a good mold release is a must. My first Bondo mold was a very nice mold. That was until I didn't use enough release, it soaked into the Bondo, and I ended up with what I can only assume was a nice cast stuck inside my nice mold.

    Google it. Seriously. There are a ton of companies out there that sell gel coat in all kinds of colors. Find a company you feel comfortable with and order it in. I highly reccommend a respirator when working with gel coats, you'll know why once you've opened the can!

    You don't have to use gel coat. I use thinned bondo instead and have been happy with the results. Smooth on and Innovative polymers also carry some urethane casting resins that work as well. PVA does a very good job used in conjunction with the wax, but again isn't 100% necessary. A couple coats and buffs of your carnuba wax will do the trick.

    PVA.....

    PVA is not necessary at all. Just use car wax.

    Although I have used gel coat in the past, I prefer IE 3030 or Fast Cast on fish molds.

    I have numerous prickly pear cactus molds made out of bondo and all I use on them for mold release is car wax and I pour bondo for the cast. Bondo on bondo with car wax as a mold release.

    On rock molds made out of Latex 74 all I use is car wax for a mold release. Pour thin layer of bondo for my first pour and then pour two-part foam.

    And with silicone molds (GI 1100) no mold release is necessary.

  7. Fiberglast. google it.

    I would seal the mold with several light coats of diluted shellac. over a couple day period. then wax it with Johnson's Paste was. Yellow can at walmart of home depot. Wax, allow to dry then buff, repaet a couple times the final buffing should show a good shine looking at the mold. Johnson's is pure carnuba.

    No PVA required!

    I like pva so you don't have problems with the wax wanting to bead up your resin.
