Hi guys & girls.
I've got a couple of questions for anybody with knowledge of coupe sunroofs...
Basically I'm having some paintwork done on my coupe, the sunroof has always been fully functional, and reasonably water tight (has leaked a little in the past, but only ever after a torrential downpour and if I've parked it on a slant, nose facing down etc) anyway i supplied the painter with a new genuine sunroof seal to fit, Hoping it would then withstand any future heavy rain fall.
The painter contacted me today asking if I could get another sunroof glass, because under the seal, the metal around the glass had seriously corroded (odd to me, because there's no other rust anywhere on the car!) So knowing I had a full spare sunroof assembly from a low mileage car, I pulled it out the garage this evening to inspect.
After stripping the seal of this spare unit, much to my dismay, it was exactly the same! To the eye with the seal on looked absolutely perfect, then under the seal, literally nothing but flakey rust!
So my questions, to anybody with knowledge on the following:
1) is it possible to buy new glass replacements? If so where from?
2) is it possible to remove the metal from the glass, treat and/or replace as necessary?
3) are there any aftermarket sunroofs that would be a direct replacement, and still do the same functions? Tilt, tilt + slide etc...
Worth mentioning there is no other rust to be seen anywhere else on the entire sunroof mechanism (only on the metal around the glass) so I'm guessing they're prone to corrosion there.
Any help / advice will be greatly appreciated. Thanks.
P.s. have you checked your sunroof lately?
Angelo.

Angelo,
This is the exact reason why your dad sent me a sunroof the last time. As far as i know, there isn't any replacement glass/frames available.
I also looked at how the frame could possibly be repaired..but the difficult part is that the frame has a small metal lip in which the seal 'hooks' on to. In most cases, this lip is totally gone and disintegrated.
I'm not sure if there are any aftermarket sunroofs out there. If there is, I would imagine that the sizing would be slightly off anyway. Probably easier to delete the sunroof in its entirety. Yeah cheers kelv, you got lucky there mate, finding an immaculate one from a UK car! I've no idea how the frame could be repaired, as you say that lip would be almost impossible to fabricate. I think I'm just going to pull the seal off the one that's on the car, treat the remaining metal and refit the seal as best I can, if it works it works, if not... Back to the drawing board and I'll have to hunt for a replacement. I'd never delete the sunroof, as it's partly the reason I bought the car, absolutely love them, specially right back on full tilt, matching the arch lines of the car I'll know more tomorrow, as the body shop is back open then, I'll send you some pics on FB

I don't see it being a problem making new frames that fit and work and don't look too unsightly! However the biggest problem i think would be removing the frame from the glass without damage, or welding the lip without damaging the glass perhaps we need to have metal panel roofs fabricated as the only viable option?
I have 2 sunroofs one has only minor corrosion on the lip on just one corner but too scared to weld it incase it damages the glass, the other spare is a bi worse but not had any time to play with them I think everybody with a sunroof is going to be looking for some sort of viable option over the course of the next few years. I see what you mean about damaging the glass, and it's not like it's a straight bit of glass you could easily replace either, as it's curved. I'm going to take my spare one to the body shop tomorrow, so the guy can have a look at it, see if it can be removed / fixed 'some how' I'll update on here when I know more.

Angelo, i’ve got the same problem. Took my seal off and replaced with a new only to find the metal frame below rusted away. I’ve been looking for a few years but unfortunately even ‘the. spare’ ones i’ve bought seem to have suffered the same as it must be a weakness in the frame manufacture. Unfortunately after many hours of reasearch I found that no one else makes a replacement/similar one as the coupe as it is unique. I have toyed with fitting a bigger new one but the cost is massive!! i’d be interested in hearing if you do find a solution, i’m waiting on another second hand one but imagine it will be similar!! I love my sunroof too but it’s starting to drip!!
inky goodness!!

If it weren't for the evident hassle involved I'd be glancing in FCSS direction to investigate a group buy but I fear it might be pretty costly.
I have been trying to resolve the 'rusty sunroof frame' issues on and off for the past 5 years, having them re-manufactured is too costly and even if we could have them made we'd need to reuse the original glass. Fiat designed the coupé sunroof as a bespoke size so Bravo. Brava etc etc don't fit, I purchased several units second hand to physically try but no joy. After market has been looked in to, issue we have here is the OE hole size in the roof panel is quite large so we're very limited to what will fit when the frame and rails are removed, after market will also need a none sunroof head lining so something else that needs to be factored in. At the moment I'd advising owners who have light corrosion in small areas to tackle it now with rust stop and paint, and for the owners with heavier rust issues to leave it closed and pull the relay so it can't be accidentally opened. It is a big problem and one that will seriously effect sunroof models in the future, even to the point of water ingress damage writing them off so some reverse engineering and some thinking outside the box is needed on this.

Joe, point we’ll made. I think I actually made my sunroof worse by pulling off the old rubber and fitting a new one thinking it’d help. The old rubber was actually holding the frame together!!! I’ve now temporarily bonded and filled in the holes in the frame/rubber with flexible black gutter sealant to hold it all together!! I would advise those with a sunroof to pop it off (only held on by a couple of screws) and treat the frame with rust prevention and some hamarite type paint. Don’t be tempted to replace rubber as it might actually make it worse!! I’ve hopefully found another that could be a bit better, they are becoming like hens teeth...
inky goodness!!

Just to add, my poxy frame has the same issue, finally bit the bullet, not as bad as I thought...but 2 of the front edges are missing in bits, but the radii are there, thankfully with some careful heat to the frame, the glass is easily separated, going take the frame into work, shot blast with light glass bead, then go about epoxy primer then repair...shite design, wish they had made the frame stainless ! I wonder if Marcus could make a replica outta fibreglass ? Bonding is easy, and whatever they used at st Cobain was poorly applied inadequate adhesive. ....knew I should have bought Non sunroof one !

What an irony this thread is. My yellow resto coupe is non-sunroof (I orefer a glass top but looks like I've dodged a bullet!). My blue sprinty has a glass roof - but I don't want it in there as need the extra headroom as its already half prepped as a track car.....
Always seem to have too many 20VT's to count......

There is a how to guide for removal of the sunroof, should you be able to refurbish the frame.

Just to add... I've refurbished my sunroof frame.... it'll never be concourse....but it's fixed. Ended up shot blasting the lot, then remade the 2 missing edges with GRP tape, then resing the lot Worked well, only pain was refitting the seal. Took 3 attempts, and certain bits needed realigning with a rubber mallet.... I left the seal out in the sun to soften, then rolled into the groove with a hockey puck. Certain bits I added some non setting butyl sealant. Just painted the back frame with gloss enamel The seal sits better than when new...but was a lot of aggro getting two of the bends to lie flat..you have to pull it into the bend... Would have been hard work if the bends had corroded away! I reckon an easier fix is to replace the seal with one that clips onto the edge of the glass and bond. Then the rusty upturn you just cut off & dress flat. Removing the frame took 10minz with a blowtorch on the metal to gently heat it to about 80deg c ... A u seal with a 10mm compressive seal would suffice.... That's what I'll do next time ! Edit : some pics of what you may see !!! rusty as hell ! I had to cut off the rust from the back of the glass too & prep. All finished Cheers

Glass came away easy...
I simply cut the old seal into 4 bits and placed n s e w to centralise, then clamped gently to the steel frame....
Easy really.
Yup, the glue used is rubbish, with a small plastic wedge, the glass came away in about 10 mins... maybe less ! Naturally, aim the flame at the steel, not the glass !!
Cheers.

Hi everyone how far should sunroof open mine only opens about 4-5inches To the best of my knowledge it's a two-stage process - the first press of the switch opens the roof at an angle, the second slides it back....I wouldn't say much more than 6 inches.
