Tried & trusted methods for leaky windscreens?

[72EuropaTC]

Whilst the weather's a bit dry I thought I'd have another go at trying to cure my leaky screen. I've refitted the screen before but I still get leaks every now and again. The body's fibreglass, so I guess some flexing is the cause of it reoccuring. Anyone got any trusted methods or tips?

Bond it in as if it were a standard modern screen having first bonded the shiny trim to the screen.
Use LOTS of goo at all points but particularly the top of the screen where the fibreglass roof is a bit "flexible"
As there is a "channel" around the screen you will have to use lots of the goo.

Hope this helps

I think the best option would be to get it done professionally, and ideally with a new rubber.
I had a similar problem with my old kit car, went along to the local autoglass for a chat and that was how we progressed.
When they fitted the new rubber they put quite a bit of black sealant in the channel where the glass sits, then fitted the windscreen and then the filler strip. Quite a bit of the sealant came out when they fitted the filler strip, but it never leaked afterwards (well for the 10 years I owned it after).

I had tried using RTV or bathroom sealant but it never sealed for much more than a couple of months.

make sure its proper windscreen sealent too- the silicone stuff sounds good, but it isnt flexible enough. The proper stuff (and its pretty nasty- goes everywhere and, from memory black) is the right thing to use. Dont be afraid to sue too much- a razor blade will remove the excess from the glass, or you can remove it with a cloth.

Aquarium silicone sealer is incredibly strong, designed to adhere to glass, flexible and clear.
Worth a try for localised repairs.

If you bond your screen in ,it will never come out without damaging the aperture.They are quite weak without the screen.Take it out again and check the aperature is good, without any old damage repairs evident .Offer the screen up without the rubber to check it is okay, no high spots, no extra thick areas of the lip and no high spots.The screen on a Lotus adds to the strength of the tub,so it should not move.It shouldn`t leak either, so best find the cause of the problem before you use loads of sealant

Thanks. I think what I have is a localised leak along the sides somewhere. The screen was well fitted and lasted a year or so before the leaks appeared. Tracing the route & source is problematical without an ensuing visit to a physio.

Arbomast Autograde is the stuff you need -specifically designed for this precise application. It doesn't set completely, so you can always get the screen out again. data sheet here: http://www.resapol.com/new/datasheets/data957.pdf

I've used some stuff called Seak'n Seal from Comma products but I don't think it's available anymore. You may find some in an old car shop it's a clear liquid which seeps into gaps and seals them. Great stuff, lord knows why they stopped making it

Here's some stuff I found on Google...

"Seek and Seal = Capt. Tolley’s Creeping Crack Cure (CTCCC)

I hope this will be useful for anyone trying to stop water leaks in their Volvo or any other application.

For those of us over the age of thirty will probably have heard of a product called ‘Seek and Seal’. My memory of this product is very positive; application was easy and the result was almost 100% successful. Unfortunately this is no longer being manufactured, I have this on first hand experience when phoning the manufactures www.commaoil.com.

Do not despair. There is an alternative called ‘Capt. Tolly’s Creeping Crack Cure’. It can be purchased from the manufactures website www.captaintolley.com or from one of the retailers listed on the site. After checking all the retailers to find which was selling the cheapest, I bought a 60ml bottle of CTCCC from http://www.midlandchandlers.co.uk/searchresults.as... From them it cost £4 plus £2 P&P including vat., others were charging up to £12 + P&P"
