I'm rebedding my hatch with butyl tape and though I would ask...
The aluminum hatch frame was screwed down with self tapping ss screws except the hinge which was through bolted. In general I think of through bolting as a better method. Any thoughts or opinions? I guess it's not like a cleat that gets pulled much (hopefully)! Is there a good reason (other than how it looks on the inside) NOT to bolt the sucker down - just to be on the safe side?
