Inquiry (采购产品): moldable rubber I have a masonary box in my backyard approx 4' long, 2' highand 1'wide, into which I wold like to insert a solid form, like rubber that wad molded to the exact inside dimensions of the box. Is there material you can sell me that I can pour into the box and extract later that would be re-usable? Got any other ideas? **** Hidden Message ***** jerry obrien 76012 Company: pdc corp E-mail: jerry@pdccorp.com **** Hidden Message ***** jerry@pdccorp.com
