Inquiry (采购产品): Linners for Heating Duct I have a 10 inch heating duct around the perimeter of the basement under the concrete floor to heat the basement. Over the years the ducting has corroded and is now dusty. Do you have any product and equipment to spray a liner inside the duct? Would you have a Canadian distributor that I could contact? **** Hidden Message ***** Russ Holowachuk T1B 2S4 Company: Personal Question E-mail: rholowachuk@canadian-fertilizers.com **** Hidden Message ***** rholowachuk@canadian-fertilizers.com
