i wouldnt do that yet, i feel your pain, dont fill it with silicone, it will retain water and rust it out faster, keep it parked under a car port or in a garage, if you just noticed the water, it mite not be too late, safe lite gan gen a new windshield if it breaks while removing it, i would look around and see if you can find a shop with a older guy working there, these windshields are very easy to replace, i got mine out in 20 minutes, cleaned the metal, welded and duraglassed it to make it smooth, put that 3m glazzing compound down, (2 tubes) , put the new gasket on the winshield , put a small rope in the groove of the rubber where it meets the body and sit the window and rubber on the frame and put the rope out, it will pull the rubber in the car and set the windshield, i did mine in an hour and a half with my friend, clean the glass with accitone too, its a pain i know, but its not the cars fault, be carefull with the beauty metal around the windshield, it will bend if you stare at it wrong
