MTfishingrods Posted October 21, 2008 Report Share Posted October 21, 2008 Can anyone tell what type of resin this mold was made of by just looking at it? Quote Link to comment Share on other sites More sharing options...
KcDano Posted October 21, 2008 Report Share Posted October 21, 2008 Could be polyester resin, with such limited info it is guess work. Quote Link to comment Share on other sites More sharing options...
MTfishingrods Posted October 21, 2008 Author Report Share Posted October 21, 2008 Yeah I know its not much info. I just saw a bunch of these on ebay and was wondering if anyone could tell by looking. Obviuosly I couldnt. So I dont expect that anyone else will be able to do much more than guess but I can always hope. Quote Link to comment Share on other sites More sharing options...
Zbass Posted October 21, 2008 Report Share Posted October 21, 2008 MT, That is definately a Bondo fiberglass resin mold. Looks exactly like 98% of the molds in my shop. How much are they selling them for? Zbass Quote Link to comment Share on other sites More sharing options...
Kajan Posted October 22, 2008 Report Share Posted October 22, 2008 Looks like polyester resin to me:? Quote Link to comment Share on other sites More sharing options...
GB GONE Posted October 22, 2008 Report Share Posted October 22, 2008 Bondo resin for sure. I have used this to mold plenty of times before. You can buy it at Walmart, automotive stores and craft stores. Jim Quote Link to comment Share on other sites More sharing options...
MTfishingrods Posted October 22, 2008 Author Report Share Posted October 22, 2008 (edited) The price looks very reasonable. 5.00 plus shipping. Looks like what they sold for. Also looks like they were very well made. I will be watching for more of his molds. I have never seen it before so I wanted to ask before I decided to purchase any.

outdooradvantage Posted October 23, 2008 Report Share Posted October 23, 2008 I have a couple of molds made from the same material, probally the same person as well. They make some nice looking baits. Quote Link to comment Share on other sites More sharing options...
roger77 Posted November 7, 2008 Report Share Posted November 7, 2008 I have two of these molds I got off of E-Bay and they work great and cost was 3 or 4 $ apeice :yay:but got a discount in shipping for both. Total was 9 something and they are resin. After I got them I bought some resin and made two of my own molds. hopes this helps Roger Quote Link to comment Share on other sites More sharing options...
Romeo D Posted February 20, 2009 Report Share Posted February 20, 2009 I bought some Bondo filler and Bondo fiberglass resin at Walmart. I mixed 75 percent filler with 25 percent fiberglass for a lead pour mold I was making. I tried using the harderner that came with the fiberglass resin, (30 drops for 12 ounces, I don't think it was enough hardener) then added some of the hardener from the filler because it did not seem to harden after 30 minutes. My question is, it did not come close to the color of the mold at the begining of this thread. With just the hardener from the fiberglass resin the color looked greyish, like POP, then with the hardener from the filler, it turned pinkish. Is there another Bondo resin others are using? Thanks, Romeo Quote Link to comment Share on other sites More sharing options...
IGOTWORMS Posted February 20, 2009 Report Share Posted February 20, 2009 The pic. of the mold above is not a mixture. It is pure fiberglass resin. On a side note, if it is cold out you will have to use a little more hardener and it will usually take a bit longer to dry. hope this helps.

Vodkaman Posted February 20, 2009 Report Share Posted February 20, 2009 Romeo. I just did a web search, as I do before working with resin, as I always forget the drops ratio, I know, I should write it down. The first doc I came across stated 12 drops per fluid ounce. This would be 144 drops for your mixture. When I did the resin/bondo thing, I only used the resin (polyester or fibreglass resin) catalyst. Everything worked out fine. Do a google search and read a few different docs, as there may be conflicting info out there, then use the most quoted figures. Best dump what you have done so far and start again.

nova Posted February 20, 2009 Report Share Posted February 20, 2009 The two problems with resin molds that I found was that if you pour a lot of baits at one time the mold will really heat up and begin to soften and deform. As well, the smell of the resin (when hot) will transfer to your baits. With small pours(less than 50 baits) you may not have a problem with this. But, if you pour all day with them you will have a problem as stated above. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Romeo D Posted February 20, 2009 Report Share Posted February 20, 2009 Nova, thanks for your information... I will be sure not to pour in this all day, just a few for my own supply for now. Actually ordered a DoIt mold for this application, but wanted to try my hand at making Bondo molds. Vodkaman, you are correct, 12 drops per ounce, that is same ratio for what I am using. I did not use enough. I read somewhere here that someone used less to help in the shrinkage. I will also try using just the MEKP liquid on my next mix of filler and resin. I am going to have to buy more of the MEKP at Tap Plastics, since I did not see it available at Walmart seperately, the little bottle that came with the fiberglass resin will not be enough for both of the filler and resin combined.

That's very interesting. Quote Link to comment Share on other sites More sharing options...
Zbass Posted February 21, 2009 Report Share Posted February 21, 2009 Nil is absolutely correct. I use resin a lot and have encountered that alos. My remody was to make more molds and cool them between pours. In the winter thatis easy. Set them on the concrete floor. In warmer months, I use a fan to blow across them. haven't had problems since then. Zbass Quote Link to comment Share on other sites More sharing options...
nova Posted February 21, 2009 Report Share Posted February 21, 2009 Zbass; I found even using 4 ten cavity molds at a time was still not enough to stop the sagging and smell transfer. I have since changed to POP molds for those baits. Wish I had all the $ I spent on resin over the years. Oh well; as long as the wife doesn't figure it out I'm safe;lol. www.novalures.com Quote Link to comment Share on other sites More sharing options...
