Hey guys, I've recently sanded and treated some minor rust underneath the cowl in the plenum area where the wiper motor etc. goes and i remember a while back seeing a Custom Z that had a solid cowl (e.g no air induction holes) and i was wondering since this area is prone to rust if it would be a good idea to fill in the holes of my cowl (at least on the driver side and leave the passenger side as is for the heater air intake.) Would this cause the wiper motor to overheat? I'm trying to figure out why the holes are there other than to gather leaves and wet slush.(even though I've treated with POR I'm still paranoid). Looking for an opinion on this, is it is a bad idea? Thanks, Sam
