Tm Customs Posted July 18, 2004 Report Share Posted July 18, 2004 If I make a mold out of plaster a paris which works well what would be the best thing to coat it with some people use nailpolish but that is stick and messy. Any ideas? Thanks, Tm Quote Link to comment Share on other sites More sharing options...
Pit Bass Posted July 19, 2004 Report Share Posted July 19, 2004 Tm, I use Devcon 2 ton epoxy to seal my plaster and water-putty molds. It's a clear 2-part epoxy with 30 minutes of working time. You can get it at Walmart. I brush it on my molds with a few thin coats using a cheap bristle brush. Quote Link to comment Share on other sites More sharing options...
bass ackwards Posted July 19, 2004 Report Share Posted July 19, 2004 I like to use a glossy high heat resistant spray paint like the kind you would use on an engine block. It protects your mold from heat and leaves a very shiny surface. REMEMBER... the smoother the finish on your mold the less texture it will leave on your bait!

charkins Posted July 19, 2004 Report Share Posted July 19, 2004 I use the engine paint as well. It can stand the heat and gives the baits a real glossy appearance. I try to use 3 light coats instead of 1 heavy coat. Calvin Quote Link to comment Share on other sites More sharing options...
Tm Customs Posted July 19, 2004 Author Report Share Posted July 19, 2004 Is it in a spray can? And does it get really hard and stay that way unlike nail polish? Thanks, Tm Quote Link to comment Share on other sites More sharing options...
charkins Posted July 19, 2004 Report Share Posted July 19, 2004 The engine paint is in a spray can. You can get it at any auto store or even the infamous Big W store. The color I get is blue, but I think it may come in other colors. It does get hard and stay that way. It seems durable to me. Calvin Quote Link to comment Share on other sites More sharing options...
Fish_N_Fool Posted July 20, 2004 Report Share Posted July 20, 2004 I paint a light coat of fiberglass resin on my molds, but I don't use plaster anymore. Durhams water putty is far superior to plaster in both strength and detail it captures. It is more expencive though. I make my trail molds out of plaster, then make a good one in Durhams after I get all the bugs worked out. I coat all molds with the fiberglass resin, It dries fast and has a great shine. I use a little asatone for thinning and clean up Quote Link to comment Share on other sites More sharing options...
Tm Customs Posted July 20, 2004 Author Report Share Posted July 20, 2004 Interesting FF I did try the engine paint it seems to work good. I may give the resin a shot too if the paint fails. But I did notice on my resin molds after about 6 months there shot Tm Quote Link to comment Share on other sites More sharing options...
Pit Bass Posted July 21, 2004 Report Share Posted July 21, 2004 Is there any particular brand of engine paint that you guys perfer ? I only tried it once and the paint never hardened. Did I do anything wrong ? Pit Bass Quote Link to comment Share on other sites More sharing options...
charkins Posted July 21, 2004 Report Share Posted July 21, 2004 Did you shake the can well? Mine is from Big W. I set mine out in the sun for several hours between coats. It's running in the upper 90's here. I did some last winter, and it did take a while to dry. When dry it gives a real high gloss finish to the baits. If it will take the heat of an engine it should take what we can dish out on plastic. Cal Quote Link to comment Share on other sites More sharing options...
cflbasser Posted July 21, 2004 Report Share Posted July 21, 2004 TM... About coating the molds with resin... If your making a two part mold, make sure you get a real thin and smooth coat of resin on the mold. My first attempt with this had some uneven areas that caused the two pieces of the mold to not come together all the way... Most of the baits turned out ok, but a few had some seapage along the edges. I was able to trim the baits, but its still annoying to have to do this. Also, i took some sand paper and smoothed out some of the uneven areas of the mold, and that helped. Quote Link to comment Share on other sites More sharing options...
