There is gushing water coming in everytime it rains, I live in FL so that is very, very common, specially in summer. It pours on the driver side but sometimes it also on the passanger side, it started with a few drops but now it pours like half a glass of water each time.
Should I take it to have the windshield replaced? A friend of mine said to put silicon on it, would this work? How do I do this? I not very mechanical enclined or very handy.
Thanks in advanced on any advice you can provide.

what kind of car?? if the windshield isnt cracked, or chipped, keep it, but seriously, it just sounds like you need a new seal, it's pobably gonna be a couple hundred to get it fixed simply b/c they have to take the windshield out and replace the seal, then put it back in, honestly, you could try silicone, but in my opinion, it may work for a while, but in time, would just accumulate to a big mess......good luck with whatever you do

If you are leaking water from the front windshield then yes silicon will work. I used plenty in Hawaii on "island cars" and it worked great. However, if you are using it on a nice car (your 3000GT) then this should only be used as a temporary fix. The front windshield is held down with glue. You may want to take it to an auto glass repair shop and have them work on it. Taking out the windshield is something you will not want to do yourself unless you know what you're doing (you can break the glass in the process). You may want to have the glass removed and reinstalled to check for rust.
