I'm using 2 layers of stocking, pretty strong, it is not indestructible though, so it will brake, but you are going to have to through it a bit harder than that on a cold frosty day, to get it to shatter...
indeed it is not the easiest of things to do, I am somewhat of an old hand at it (this resin thing, that is....) , and even I had a boobo with he first one I made last week... ( been a while)
the one therein those pics, is number 2 and number 3 is for a 120mm fan on the same oil-cooler. it's right here on my desk, ready to get drilled and hole'd for the fan... WANA see????
