Windshield/back glass leaks.....

Just got back from picking up my car. Both glass are new with new gaskets. Zero rust, car was just painted. EZ, the body guy, had the glass company out 3 times after the initial install due to leaks. He gave up on the leak problem. I have not observed it yet but he said there is a very small drip on both. No more vent boxes in the front. EZ said that the glass guy claims that there was some channels up front that allowed the water to drain into the vent boxes and he sealed them up. Anybody else have persistant drips?? There is a guy in town that is supposedly real good with old car glass that I might go see sometime. Have to remember to look for different trim clips before hand as the Year One pieces are not that good...
