Kajan Posted July 27, 2008 Report Share Posted July 27, 2008 Hey, I'm new here, first thread on this forum, had a question to what brand RTV is prefered, and why. I have always used the one from Miniaturemolds. It lasts, pics up detail, but is kinda tough to mix. Was wondering if any of the other brands are better. Quality and durability to me would be a must. Then ease of mixing the 2 parts. I have been making my own molds and lures since 86. Started with resin then went to RTV. Thanks bou'cou' Quote Link to comment Share on other sites More sharing options...

Kajan Posted July 28, 2008 Author Report Share Posted July 28, 2008 (edited) Ma' I don't think you understand, I make all my molds my self, all my own designed lures, I was hoping some members of this forum might of tried differant brands of RTV to make molds from. Someone might know the pro's and cons of differant brands. Compron' Edited July 28, 2008 by Kajan Quote Link to comment Share on other sites More sharing options...
King Bait Co. Posted July 28, 2008 Report Share Posted July 28, 2008 I think they are pretty much the same Lure Craft, Del-Mart and M-F all sell RTV to make your own molds. You can get diffrent hardness of RTV from places. Its pretty much who you like to buy from. I have Lure Craft RTV molds and I have some made with M-F RTV and they work and feel the same. I haven't got any molds made from Del's RTV yet so I can't say what his RTV is like (maybe he'll send me some:lol:). I think some of finfever's is from Del's and they looked the same as Lure Craft's. Hope that helps a little bit. Quote Link to comment Share on other sites More sharing options...
Kajan Posted July 30, 2008 Author Report Share Posted July 30, 2008 Thanks King, Yea I figured there would of been more people who have tried differant brands. Yea I use 10:1 ratio and Firm Silicone Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted July 30, 2008 Report Share Posted July 30, 2008 I believe alot of guys are using this made by Smooth On OOMOO™ 25 & 30 1A:1B Mix By Volume Silicone Rubber Quote Link to comment Share on other sites More sharing options...
gunnie3035 Posted July 30, 2008 Report Share Posted July 30, 2008 I like the O-30 better. It gives you a little more time to throughly mix it. I never could get the 25 mixed well and still have it in a pourable state w/o air bubbles. Plus Oomoo is a 50/50 mix, none of this 1 cup to 6cc's nonsense. I'm not bright enough to follow those type of instructions. Quote Link to comment Share on other sites More sharing options...
RipLip Posted July 30, 2008 Report Share Posted July 30, 2008 Good answer Gunnie. O-30 makes it a little more user friendly. Quote Link to comment Share on other sites More sharing options...

Kajan Posted July 30, 2008 Author Report Share Posted July 30, 2008 Do y'all know if the buckets each hold one Gal or each 1/2 gal???? Quote Link to comment Share on other sites More sharing options...
redg8r Posted July 30, 2008 Report Share Posted July 30, 2008 I know that's confusing. I spoke with a smoothon rep who told me the gallon order (pictured above) totals 20.7 lbs. Which I'm guessing is 2 gallons. Liquid weight varies by the density of the liquid, so I can't venture a positive answer. Quote Link to comment Share on other sites More sharing options...
Delw Posted July 30, 2008 Report Share Posted July 30, 2008 they look like 1 gallon buckst to me. and the weight jerry gave sounds about right 9lbs per gallon on RTV plus bucket weigth of around a lb. remember though its sold by weight so it might not be completely full.

Kajan Posted July 30, 2008 Author Report Share Posted July 30, 2008 Ma' thanks, Ya'll cleared dat up LOL Looked like each bucket was 1 gal, and might not be full. They did not explain well. Quote Link to comment Share on other sites More sharing options...
gunnie3035 Posted July 31, 2008 Report Share Posted July 31, 2008 If your not pouring a boat load of molds I wouldn't buy a gallon of each. It does have a limited shelf life once it is opened. I'm not sure what the shelf life is, but I've let it sit for a month or so w/o any problems. I think they sell a pint sample pack for $22-$25. You can pour quite a few molds from the sample pack if they are not too thick. Quote Link to comment Share on other sites More sharing options...
redg8r Posted July 31, 2008 Report Share Posted July 31, 2008 I'm not sure if they have changed their policy over the years or not, but they used to only allow a single sample or trial purchase per person. I got around it by buying a trail kit on their old shopping cart & when they recently switched over to a new cart system, all records were lost/incompatible, so I ordered another one. If they have indeed changed that policy, good on em, but I know that their distributors stock those same kits on the retail shelves for hobbyists.

Kajan Posted August 1, 2008 Author Report Share Posted August 1, 2008 Yea, I am gona try that brand and get that ammount. I will need to get more. My lures are fairly large, after first pour, I set the timer to 7 min. then I can take lures out and put in ice water. So they are decent sized plastics. Fishing here we use bou'cou' lures, so, I want enough lures that I can make few hundred in short time. Quote Link to comment Share on other sites More sharing options...
King Bait Co. Posted August 1, 2008 Report Share Posted August 1, 2008 I was at work today and was stocking my silicone that are tinners use and I noticed that we have RTV in a tube. I wonder if I could make molds with it. The only problem I could think of was its brick red. I don't know if it would stain the plastics or not. It is for high temp 500 degrees and is flexable after it sets. I may try it next week I forgot to grab a tube today on my way out or has anybody tried that RTV yet?

Spike-A-Pike Posted August 1, 2008 Report Share Posted August 1, 2008 If it's made by Dowel Corning, it works great for sealing the engine bay and insulation blankets for jet engine "hot sections". The stuff we used soft cured in 1 hour and fully cured in 12 hours and stayed flexible at least 24 months and peeled clean with a minimal effort.
