The Diablo Skid Plate is the perfect solution if you know you will be dragging your kayak. Simply heat and apply the plate to the keel to preserve the bottom of your Diablo.
Diablo skid plate comes with no directions. When you do get them you find that they are to follow. You have to heat it but if you heat to much the backing come off and it will not work. I threw it away and wasted 110 dollars.
