So, use PE on the window to seal joint. What would you recommend to use on the seal to metal joint, same stuff?

Secondly, should I put the PE on the window to seal joint before I put it back in the car, or after? I've heard that some people put it all back together, then lift up the outside of the seal and squeeze sealant in the joint, and I've heard others seal the glass to rubber seal joint before reinstalling in the car.

Thanks again,

I installed the screen dry, using a little soapy water to get the screen in. Then the next day when it was dry I masked the car and window, then squeezed PU sealant between the rubber and metal, then between the rubber and glass. Let it dry until the sealant is just starting to set and unmask.

You will need a lot of rags and white spirit or turpentine to clean this stuff up, it is messy and if you leave it on the paint is very difficult to remove. Glass is easy just use a razor blade to remove it from glass.

This is something I will have to look into. I know from past experience that taking a bonded screen out is not easy and as mentioned unlikely to be reusable. My problem is the rubber looks obviously knackered and needs replacing. The car needs respraying so need to decide on a best way forward.

Thanks for that Warren. If time permits I'm going to put it in tomorrow and will give it a few days to dry then proceed with the PE.

Thanks!

I thought that also, but then referred to the shop manual, it tells you to place the seal center it on the bottom of the frame opening and work it evenly around to the top.

I first put a bead of mastic around the frame (clean well first of course) and let it set up for a couple of minutes, then (worked a bit backwards) started at the top center, and worked out to each cornoer taping to hold in place as I went (otherwise it may fall down). then worked down the sides and then on the bottom. if you have some bulging or what seems like extra work from cetnter of top and bottom to each corner, that will take out the slack and get the seal into the corners, then let it set up a short before removing tape.

The glass will be placed into the bottom grove first, and I used a tool called a bone(automotive body or glass shop may have one to sell ya, will post a link what a bone is) to help getting the seal lipped on the glass. and worked around each side then on the top. check inside to see that seal is over glass.

when done with that I then mastic into the seal on the outside only. tape off around the body and add mastic between the seal and frame, the mastic between the seal and glass.

I didn't do mine this way, because most of the seals do not fit exactly as the original and this can cause the screen to not sit in the rubber correctly.

I had no trouble doing it that way and the seal fit perfect

Daverb, thanks for that! I'll give some thought to which method to use...

Looks like Friday is the day I'll take a swing at it.

I've read that some people use insulated wire as the "string", and others use weed wacker line. Since I don't have a week wacker I guess I'll use wire since I can see using that again.

I would take it one isn't any better than the other?

Thanks,
John

Just a follow-up on my windshield replacement. Due to the injuries sustained from a separated shoulder, I was not able to get the windshield back on myself. I hired the job out, and the new seal looks to be properly installed. The bad news is that there is still water leaking into the car.

The leak becomes visible when it drips from somewhere under the dash onto my (drivers side) feet. In turns, it will drip more, and I can see water running down the side panels directly below the where the dash ends.

This only happens after a good rain.

The issue isn't the a/c compressor, since I removed power from it to help isolate the problem.

Getting back to the windshield, while it looks like the guy did a good job putting it in, I have no idea if he used any sealant. So, next step is to get a hold of some polyurethane sealant and apply that.

Any recommendations as to a particular brand?

Thanks!
