I've bought new rubber, and new glass. The rubber and glass have been installed on my car. Its been about a week since the glass has been installed, but there are places between the rubber and the body where the rubber is not laying flat on the sheet metal, and there are places between the glass and the rubber where there is a slight gap between the rubber and the glass. I thought maybe since the car is sitting in my heated shop, the rubber would lay down and seal, but its not happening. The problem is mostly around the sharp corners where the rubber can't make the sharp bends. What do I need to do to get the rubber to seal to both the glass and the body? Do I use weatherstripping glue to hold the rubber against the body and the glass? The car has to go outside soon, and I really don't want to watch the water sit, or run into the car when it rains. The car sits outside normally. Gene
Shoot a little windshield urethane between the body and rubber, and tape it down overnight. On the rubber to glass, you can use the urethane also, or black silicone. Cut a small tip on the tube and stick it between the glass and rubber. Run about an 1/8" bead in there. Push the rubber down so the material squeezes out. Clean up the squeeze over with a razor blade, then tape the rubber down to the glass if there's a gap. Take the tape off tmrw
That's why i said to use urethane between the rubber and body. Never put silicone against paint or metal. Seen it done so many times with destructive results in my 30 years of bodywork and autoglass experience.
Does windshield Urethane come in a squeeze tube, or a caulk gun tube? Where would I get some? All the guys at Orielly's wanted to sell me was silicone stuff. Gene
Go talk to your local windshield place, and ask them for a tube that will fit in a caulking gun. It can be pretty stiff coming out, though.
I've never seen it packaged any other way than in a tube. You should be able to get 3M window weld at the parts house, it's a thinner viscosity. The high viscosity is fir supporting the weight of the window so it doesn't sink to the pinchweld. But if you use HV, just warm the tube up good and you'll be able to pump it with a hand pump caulk gun.
X3 on Urethane but have plenty of towels/rags and lacquer thinner handy, that sh*t goes everywhere ya don't want it to.
Black silicone can be used to fix rubber molding. You can contour it very nicely with a plastic spoon as you you keep cleaning the silicone off the spoon after each pass of "sculpting".
Silicone works great as a sealant, not so much as an adhesive. And the acidity will eat paint causing corrosion. But it's a good quick fix
