Any of you guys that do metal roofs ever apply ( and have luck with ) some type of wax that helps to keep dirt from attaching to the roof so quickly again ?
I am quoting a metal roof at a farm, and they wanted to know if there was something like a car wax that could be applied that would hep to keep the dirt from attaching again right away.
Powerwash.com sells a wax that is used to keep concrete from sticking to the truck. 5 gallons is $59. That is what I will use unless some one gives me a better option.
