Amazon Basics 6-Piece Trigger Clamp Set – 2 Pieces 4-Inch, 4 Pieces 6-Inch … I used it to lube all my canvas zippers on my upper deck of my trawler. It took the entire can. The zippers work perfect, but the McLube recommends a 2nd coating. At $30 this gets a little pricey which would be my only complaint.
