A major mistake in the 1980's. 

Our regular high quality structure sheet producer was on strike so we settled on the number two supplier. After only two years, failure began. Notice how discoloration occurred rapidly and unevenly. 

Buying quality poly and structured sheets is so important and only increases the cost of the project by a few cents US per square foot.
