    I blew out my rear quarter glass last week and it shattered into a zillion parts. I've got a new glass (don't ask -- it was pricey) but I'm wondering if I should attempt to mount it by myself.

    It looks like the glass is simply glued into the frame and there are no additional gaskets or seals necessary. The new glass came with a nice rubber gasket already installed around it's perimeter. So here's what I'm looking for:

    1. Should I attempt this myself, knowing the car will continue to be tracked and driven hard?

    2. Is this (see picture below) the proper adhesive (Permatex 66b Clear RTV Silicone Adhesive Sealant)? If not, what is?

    3. Any tips? Or just glob it on, press the glass in, and clamp/tape until it sets?


    Thanks in advance!!

    Were any of those rear side window panels made of Lexan/Lexar on the TSs/TBs? I'm pretty sure that the rear window itself was Lexan on the 348 Competitizione...seems like a cheap/easy way to save some weight as well as handle racing stress.

    Yikes - I would guess that Permatex clear RTV Silicone is COMPLETELY the wrong product for installing your new glass. I would seek the advice of a good body shop, or auto glass shop, or even the Ferrari dealer (!) before attempting to install with silicone. With the proper product, you should be able to mount the glass yourself. I'm sure it's a messy job.

    Tell us what happened - how did your window get smashed?

    1. Good thing I didn't install it or try anything yet ! Would this be better? http://www.levineautoparts.com/3murwiad10fl.html


    2. It just popped out on Turn #5 at VIR during the last run of the day. It looks like a P.O. probably removed the window before to install some speaker wiring along the sail panel. I suppose the old sealant got brittle, and with the windows down there was lots of outward pressure on the glass. That, coupled with body flex, probably finsihed the poor thing off. It's nothing but shards of sand now. The new window is still wrapped in Ferrari tape downstairs.

    ND: The Lexan ones don't seal the same way -- they're scewed or riveted in. Last one I saw on a true Challenge car looked like it would leak all day long. Mrs. JRR would not approve of that!

    That product looks much better than silicone. But without reading detailed instructions, I'd be a bit cautious with it. The adhesive may need to be preceeded with some kind of metal prep, primer, sealer, whatever. And it may take a special product for cleanup.

    I think you can go to 3M USA on the net and download product info in PDF format.

    I know the guy who installed my windshield spent many hours of prep time before he actually installed the new glass.

    Yup! that is the stuff. You need the 10oz caulk gun to get the stuff out of the tube

    The best laid plans of mice and men....

    I didn't bother fixing it myself. It's too damn cold in my garage. I drove over to our local auto glass place (with a really nice radiant heated floor), and they had the glass in and properly sealed within 30 minutes. Between the prep and primer, I probably wouldn't have done as "correct" of a job. $79 and it was done. The price of the glass? That's a whole different story.

    Case closed.
