Anyone know how to fix those cargo area covers that roll up. Mine works but not the way it should, is there anyway to tighten up the recoil? So it stays tight? When it is extended it doesnt draw back in, needs to be fussed with in order to get it to roll up.

Like a window shade.
Stand the cover up on its end with the larger end up and push down to release the lock. Then roll the vinyl cover to tighten the spring. Make a few 360 degrees turns then check it.
