Inquiry (采购产品): PVC tarp I purchaced a Northern Industrial 8X10 Charcoal Gray Waterproof PVC tarp from Northern Tool. The very first time I used it, the glued or welded seem came apart, about 13 inches. I contacted them with no help as to how to fix it or replace it. Said it had a 30 day warranty. Also said there was no phone # to call the manufacture. Very frustrating. It is a very good tarp. I just want to fix it. Can you help me as to what to use to repair it. I would appreciate it very much. Thank you, JIM **** Hidden Message ***** Jim Kent 43220 Company: Personal use E-mail: www.winswiper7@aol.com **** Hidden Message ***** www.winswiper7@aol.com
