I received the free sample of Shapelock today via USPS! I immediately put it to use on a project I've been working on for a while & it has worked very well! There are some draw backs that I experienced that I thought I'd share. The plastic melts very well in water at 150 degrees Fahrenheit, & stays pliable to 130 degrees. But if you are going to manipulate it as it cools the workable time decreases rapidly. I was able to extend the moldable time by constantly submersing the project back into the 150 degree water which causes it to resoften to a workable consistency. It can constantly be worked as long as you continue that process. If you have molds of helmets, etc. I see this product being very useful with one exception. The cost to do major quantities of items will be quite expensive, but it is plastic which makes it blend into uses with Playmobil more readily. To do a moldable part would require melting a measurement of the pellets @ mashing them together into a ball then inserting the softened material into the mold & trimming the excess. It can be reused over & over with no waste from the trimmed access material, which is another great selling perk. On a scale from 1 to 10, I give this product a 7.5 for ease of use, 8.0 for being a reusable plastic product, 5 for length of time it stays pliable before needing resubmerged in the 150 degree water. When I get ready to paint it, I'll let you know how well it performs in that test.
