I've been hearing fluid film praise for a long time, but yesterday I finally made the purchase. I'm in the process of painting and refurbishing my trailer. The fluid film has come in handy spraying the channel where decking sits, the leaf springs, under the tongue where I could get any paint, and other small areas. Only time will tell how it holds up, but it was a joy to use. Can't wait to buy more and make my life easier. I'm a believer!
