SHK is absolutely right. A good plastisol is a personal preference only. Start out by asking for samples. Also question each supplier thoroughly on their experience with international shipping. Companies that have been in the industry a long time will be more experienced with the different ways to ship and one might be more economical than the other. The samples may be free but you may have to pay for the shipping. From experience I can tell you that Lureworks makes a very good economical product and are one of the largest plastisol suppliers on the market and have been around for a long time. But some people have had trouble with it and some have not. Also I used Lurecraft for a long time too. It's a very good product. You'll find some settling on the bottom of this product, but it incorporates real easily when stirred well. Just remember to stir it everytime right before you use it. I've also tried MF, there's no settling on the bottom, but I don't particularly care for the fumes that come off of it. A very good ventilation system is a must if you're going to use the MF products that are out there, also they're rather expensive. I've also tried Calhoun's, but it was probably 3 or 4 years ago. It was ok, I didn't particularly like the smell of the finished product and when demolding the baits, they felt sticky. This seemed to go away after curing overnight. This is all the advice I can give from my personal experience. I have used Chemionics but it seemed to me to be basically the same as Calhoun's, as well as Marchem. As you can see at some time or another, I've tried all of them. But keep in mind other people have used these same products without any of the issues that I had. In my opinion, samples and testing would be the best way to go.
