Anybody have any tips on how to get the bottom windshield moulding to sit nice and flush with the windshield? When my wipers park the passenger wiper blade catchs the moulding and hooks on. Driverside is not that bad but could be better. Can i shim the screw side up/ or do you silicone the moulding down? I assume my moulding might be tweeked a bit (don't think the factory did anything special) but don't know how to go about straighting/curving it. Thanks.
