Urethane rubber seal on windshield installation Options

[shoguneagle]

Ok, I have had my windshield installed with urethane sealant and rubber seal. Prior to this installation, I had another 914 sealed the same way. I do not want to get into whether to use original windshield installation methods, etc.

The problem relates to the lower corners do not want to lay down and flatten out. I have used heat lamp, tape, etc over extended periods of time. I have even used gorilla tape to hold the rubber seal down. It just does not want to stay flat. The problem relates to how can solve this problem and keep the rain/water out of the windshield area. I have come to the point of using two part urethane seal/glue and tape/weight the corners down. When considering methods such as this the job usually gets sloppy and does not work well.

I need suggestions on how I can get the rubber corners to lay flat and stay flat. Any suggestions or knowledge is greatly appreciated.

Thanks,

The best way to stop the corners of the weatherstrip from buckling up is to use a T-profile reveal weatherstrip. The outer reveal is flat with a pecker that should sit in the valley between the glass and channel. The pecker keeps the strip from sliding on the glass at the corners. You can trim the pecker short if it bottoms out and sits high.

It has to be installed relaxed and long or as you chase the molding around the glass the corners shorten and lift up because they are taught.

If you are using a flat reveal molding with no T profile start with one top corner and let it set. Work your way across the other top corner and use 2 inch masking tape as you go. Keep the corner radius's loose. Lay the strip as you go and guide it straight, don't tug. Your seam should terminate in the bottom edge middle of the glass. You can put a dab of urethane in the seam for appearance and smooth it with a latex gloved finger.

If using urethane to set the molding use as little as possible -just enough to get bead contact with the rubber and body. To fast cure the corners while installing use a spray bottle with plain water. Urethane is moisture cure.

Realistically the molding should have bond to the glass and not the body. You want to be able to lift the reveal slightly with a trim stick to blow air under the reveal to clean any crud out in the future and driving air to force any water out on its own.
