I read on some forums about applying wax on vinyl siding to help prevent mold and mildew buildup. I jsut got my business started up and I was wondering how would I apply such an additive? would I make a dilution of a liquid wax chemical in water then inject it (I use similar product as the X-JET; so bypassing my pump)... If yes, then what wax chemical do I buy?..... or is this just a bogus thread on a forum that I found.
