Hello
I have bit of a problem. On my pick-up truck I have a snapless soft tonneau cover. It has a plastic strip that fits into a groove in the aluminum rail along the sides and back. The edge of the cover then bends down and is held by a rubber strip that fits into another groove. The idea is that the rubber holds the lip of the cover down, preventing the edge from lifting and releasing the plastic strip from its groove (as long as the edge is down, the edge can't lift and the plastic will hold).
On one occasion in high winds I had the cover let go on me. Since then I constantly check it and on occassion I find it has lifted slightly. The problem is that the rubber is not holding in the groove in the aluminum rail as much as it used to.
Is there anything I can treat the rubber with that will make it stick in the groove - require more lift to pull it out? It can't stick too much as I have to be able to lift it when I want to. I don't want it to grab the rubber to the point it tears it off or does other damage. I'm thnking of something that will increase the friction/provide more suction to hold it in place better.
Hope I've made this clear.
