Lower windscreen seal
Discussion
Hey you can tell I'm back, here is another, my lower rubber seal is perished so i ordered a new one, but I'm getting conflicting info on how to fit it, the old seal itself has clearly been stuck down somehow with silicone, but according to the guy at Motaclan, it just squeezes in with no form of sealer required as per factory fit. When I done an AI search the instructions were to drill the 3.5mm rivets out the scuttle and silicone the new one down, so who is right? I must say I don't always trust the A I search when it comes to my Chimaera as it says (or it did once) that you have to take the central console out to remove the door card.... I know exactly where that came from, it was one specific clip on youtube I saw once where the guy was doing 2 jobs on the same video... however I don't trust it lol
If AI is correct and i drill rivets out, presumably i could do with a stopper on the drill as i don't know whats under there? and is AI right with the rivet size?

The lower trim is a T profile. It's pushed into the gap below the windscreen when the glass is fitted. Some ooze plus a bit more PUR helps keep it in.
To fit a new trim you have to remove the existing product from the gap and start again. Removing it is not easy and comes with considerable risk of damaging the glass or other parts of the car. Given the best tool for the job is a Stanley, there is also risk of personal injury.

So does the scuttle have to come out to make life easier? You say start again, does the windscreen have to coms out?To fit a new trim you have to remove the existing product from the gap and start again.

No, it can be done with everything in situ although much will depend on how well/bad the windscreen was fitted in the first place. No need to remove the scuttle. Worst case scenario is the windscreen has to come out, but very unlikely for a bottom trim.Post images if you have any.

Looks like the scuttle needs to come off, it's real tight in 1 place, maybe shave a bit off the scuttle, besides I could give it a refresh while its off, a nice lick of paint. So AI says its a 4mm or 3.5mm pop rivets, or 4mm peel-type rivets, mine just look like pretty small rivets, I don't want to be drilling the wrong size
All your trying to do is drill the head off the rivets and then tap the rest through into the car. They will find a way out of some hole or other 
Just use some new Stanley blades to clean the Channel out inbetween glass and body, trial fit the new rubber then clean everything up then use a mastic gun to refill the channel slightly lower than both glass and body line, re fit rubber into the fresh mastic, clean up any over spill then let it set.
You mind find a bonus in there will or should be little chance of water getting in the car via this area afterwards.

Yeah but I don't want to drill to big a hole, so wondered if anyone knew.... and yes I've been scraping like a bugger for ages, but one area is so tight, I've no idea how the original seal got in there, the Stanley blade is scaping the bottom of the windscreen it's so tight. I've even tried silicone remover, but a lot of the rubber seal has been left behind in the channel making it a pig of a job. So I thought if I can carefully take the scuttle off, it might make it easierJust use some new Stanley blades to clean the Channel out inbetween glass and body, trial fit the new rubber then clean everything up then use a mastic gun to refill the channel slightly lower than both glass and body line, re fit rubber into the fresh mastic, clean up any over spill then let it set.

Correct it will help slightly.
A drill bit slightly larger than the centre hole in the rivet head should see you drill through the head until it becomes free then stop drilling. Remove all rivet heads this way then simply pull the grill off. This should now leave the remaining part of the rivits exposed in the body of which you now simply tap though and into the car. You can now just use the same size rivits into those holes when replacing the grill. You don t drill the whole rivets out is the point. Don t let the drill go into the body or you might open up the holes.
Probably around 5.0 or 5.5 mm bit will be large enough to cut the head off the rivit.
Number 1 tip
When putting grill back on put some sealant in the holes just before you put new rivits in. Stops a known water ingress point on the car.

I'd leave the scuttle in place. Scrape off any lumps, and give it a good wipe down with IPA. Polyurethane will stick to polyurethane better than any other substrate.
unfortunately it has to come out as the blade is scraping the class in places it's that tight and I believe new windscreens are over 700 quid?Gassing Station | Chimaera | Top of Page | What's New | My Stuff
