I was told today by a young man that does full line mechanic work on all brands of mowers and also has 3 Scags running full time some information I thought very interesting. His father owns a NAPA parts store and has a bedliner spray he said worked better than anything made for stopping grass build up under a mower deck. He has it under all his Scag decks and said the difference was unbelievable until you actually tried the product for yourself. He cleaned his decks very good and sprayed it on every piece of metal under the shell making sure all the crooks and corners were covered very well. The covering sets up very hard and nothing can change the coating, he gave me the impression it was as hard as steel and grass did not want to adhere to it's surface. Anyone out there ever heard of this before?
