Hi,all. My first post on Thunders, reading for quit some time though. This thread inspired me to make some sleeves of my one. As my supplier at the time only had ecoflex 0010 at stock, I made them out of these. A great improvement from what I used, but I’ve goth one problem with it and that’s that the end-product stays sticky and it tends to permanently stretch over the diameter I poured it in. Any of you experienced this? I’ve red the FAQ at smooth-on and did it as far I can see by the book. Note: As I don’t have a hi-tech scale I measured the components by volume.
