That film that develops on exposed grease is why I used it on the golf course. To keep it from leaking or dropping blobs of grease on the highly manicured turf. The golf course I was the shop manager at was built by Pete Dye. Same man built TPC at Sawgrass. It was 25,000 down and then monthly fees on top of that. Every preventive measure had to be taken to keep up a tour quality course.
