Glue on Glass

[dville]

Hi there! Very new Fiat owner here. Never took shop in HS, never worked on my car, but here I am - in love - and starting to think about upkeep and repairs. Easy question - what glue would you recommend to reattach the lock assembly for the vent windows? Mine just fell off (luckily not while driving). I'll have a multitude of questions in the future, but I want to try and figure most things out. Next project is fixing the speedometer cable - that went snapola when my son turned it the wrong way I'd attach a pix but I can't figure that out, either.

i would use epoxie

I initially used rear view mirror glue, but it didn't hold. I then used JB Weld - a small amount lightly clamped overnight. So far it has held with no issues on both sides.

in the stained glass area has a chemical that eches glass using acids
if you want a permanent addhesion tape off the area a bit smaller than the mount
brush the acid on and let dry.causing a textured glass surface then use epoxie
everything needs tooth to hold glass and crome are some of the smoothest things on a car.

all gules have a cracking point
the slowest cure rate is the best.joe

The glue that windshield shops use to install the rear view mirror button will work. You have to prepare the surface properly and follow the instructions for the glue. I have seen rear view mirror glue in stores but I am not sure if it is the same stuff the pros use. Maybe take it to a glass shop and use their stuff.

I used 15-minute epoxy to re-attach my vent window latches. One stayed, one fell off after a month, which was fixed with a little piece of fine emery cloth on a finger tip or pencil eraser to roughen the glass (who wants to accidentally drip acid on their paint or interior?). BTW: First, scrape the glass with a razor, then clean it with a little acetone on a rag. Acetone does not leave a residue. Smells good too
Hold the latch in the position where you want it. On the outside of the glass, draw a circle with a marker where you want the latch positioned. It only takes half a drop of epoxy. Do not later scrape off the excess epoxy or it will make micro-cracks beneath the latch and will be a weak application. Put tape, a piece of a paint stirrer or something on the outside to keep your clamp off the glass. I also put a piece of painter's tape on the latch where the clamp touches so the chrome doesn't get scratched. Let it dry at least several hours for a complete cure, over night is better.
