Inquiry (采购产品): Protecta Skid Guard Mat I am curious as to how long it takes for this mat to become flat? I have had it sitting on the floor inside the house for a week and it is no where near flat yet. I still do not understand why it was folded in the box rather than rolled. But all those corners from the fold are just all very visible. Is there something I can do to make this thing flat enough to put in the bed of my truck? thanks depley **** Hidden Message ***** DeWayne Epley 30102 USA Company: home E-mail: depley@mindspring.com **** Hidden Message ***** depley@mindspring.com
