non-gripping glass channel

[littlejim]

Can't remember where on the forum I brought up the topic of my window glass only winding down on days when gravity is high. The experts have advised me to give the channel it sits in a nip up to make up for the rusty metal that has disappeared.

Today while buying my Weetbix I met Graham who restored his frogeye Austin Healey, he suggested I fill the channel with silicone sealant, the type you use on gutters. Boaties use one of the Sikaflex silicones to 'glue' bits on to their boats, so the concept sounds sound.

Might do both. Should be re-dismantling the door in the next couple of days.(You get better at it the more times you do it.)

This is not a job I've done before, but from what I've read, it doesn't seem

to be an easy job to get the windows lined up properly, and often further

adjustment and fettling is required.

Seems like you have a bit of experience in that area, but if you use a sealant,

you'll have to get it right first time, won't you?

Jim bear in mind that some of the sikaflex products are better than others. Probably the best one for that application is the one that windscreen fitters use for modern car bonded windscreens. When you are happy that you have the channel in the right place make some marks and clean off the bottom of the glass and the channel with spirit wipe and allow to dry and then apply the sealer to the channel and ensuring that your marks line up fit the channel. Leave overnight and the channel will never come off again.(Have you ever tried to remove a bonded screen )

Edit having read Alans post, if you line the glass up correctly immediately after fitting then you should be ok as that stuff takes a while before you cant move it though it is temperature sensitive. (Would take a week to go off with the temperature in my workshop this evening )

Thanks once again Alan and Stuart. The glass is currently in the door and winds up OK and down with a bit of help, so I'll mark it and the carrier in its current position.

I'll be using one of the domestic silicones that I already own. I don't think it needs the specialist marine Sikaflex which I've used on the boat down the coast. The glass carrier provides a large area for the silicone to grip so the domestic one should do the job OK.
