I recently purchased a used 1986 boat. Its a runabout and i tried to install the cover for the front and it seems to have shrunk. Any tips on streching it out? i can get prob 75% of the snaps in.....some of the rest are real close.....some are close to an inch away from where they should be. I tried putting it in thr dryer for a few minutes but that made it worse (oops). now i am hanging weight off one of the snaps that is short. do you think this will work? Thanks
