Currently travelling and noticed a few days ago the headlining above the offside "A" pillar seems damp to the touch. I've got a sneaking suspicion the windscreen seal is maybe leaking slightly. The basis for this suspicion is the headlining dried out over a couple of days despite there being heavy rain when I had the external screen covers on and pushed tight in under the luton. I'll test it with a hose later once it's dried out again to confirm.

Assuming this is the problem I'm currently awaiting a quote for removal and resealing of the screen when we get home however what's the best temporary fix pending this? And don't say drive around with the screen covers on!!!

It's a 2013 Fiat Ducato based vehicle and the screen appears to be "sat" on a rubber seal leaving a channel of around 6-7mm wide by 3-4mm deep. Given this channel it's not going to be easy to try and make a temporary fix with duct tape. Guess doing an overseal in the channel is probably the easiest solution but what sealant to use? Would guess "bathroom" type silicone is a no-no so what do the experts say?

The screen will be bonded in with an adhesive grant... that will be what you are refering to as the seal... a bed of adhesive.?.
The edge of the glass will sit proud of that creating the chanel you refere to... or thats what im visualising...
Can you not do as you suggest and run tape from body over gap on to the glass .. but i suspecr you would have to run it round the whole screen to be effective if you are driving..
Dont think the fitters will appreciate you using any sort of mastic if you want the screen removed cleaned and refitted... the non setting mastics would make a right mess and the pu adhesives are a non starter...
Silicone is most probably your best bet if thats the route you take but personally i wouldnt..

So we had a very small windscreen leak and I used this stuff which I have
used in dingies as well.

Amazon product

So far it has been successfull but I did ensure the screen and surrounding seal was very dry (a few days in 35degress heat sorted that out!) and I applied the soltuion about 5 to 6 times. We have been in some torrential rain storms since then and all good but I will wait until the end of the winter to be 100% sure!

Apologies for considerable delay in getting back but have been travelling and just got round to, hopefully, fixing.:(

Anyway, tried Capt Tolley (thanks @clanjones ). Used a syringe to apply however the "hole" was too big and the stuff appeared to be just running through.

Guy across from us was getting his windscreen replaced in his car so oft I wanders to have a word with the fitter. He wanders round to the back of his van and gives me a "big sausage" (no other word to describe it as that's what it looked like) of the adhesive they use to secure a new screen. How much? Behave yourself!(y)
Filled the gap at the corner where I thought the seal had eased away from the bodywork and after dried applied some more Capt Tolley to finish it off. It still leaked!:cry:

Resorted to using 3M duct tape (and a wee bit of blu tack at the end to seal the channel!) as suggested by @andy63 as an interim fix and it worked so confirmed my thoughts it was a windscreen leak and not from the rooflight \ marker lamp \ etc as suggested by manufacturer!

Upon closer inspection noticed a tiny gap just below where the seam joining the A pillar to the windscreen "lintel" is. So, squeezed in a bit more of the adhesive stuff and finished off with the Capt Tolley. After playing a hose on it for 5 - 10 minutes it still seems bone dry inside so .........(y)

Many thanks guys for your thoughts.

ps Autoglass guy said nope to resealing (as they guarantee for life!) so would need to be a new screen with the potential problems this could bring and nope not covered under insurance! Cost could be in the order of £300-400!:eek:(n) The guy fixing the neighbour's car screen said it would be around £150 for a new screen including fitting but will stick with my "temporary fix" and see how it goes for now.(y)

So far Captain Tolley has cured the small windscreen leak we seemed to have. Fingers crossed!

Worthwhile being in the the toolbox.
