View Full Version : What glue to mount a high-mount brake light? (Automotive)

T'other day when driving our 30yo Magna into town I glanced into the rear-view and spotted the brake light detach from the top of the rear window and dangle by the wire.

Nothing is damaged, it's just perished glue. It appears that a pair of small plastic clips were glued to the glass, then the brake light clipped onto those.

First thought was to epoxy 'em back on... but I suspect that with the hot/cold cycle on glass that'd quickly fail. My next thought was silastic suitable for glass. But on cleaning the interior & clips I noticed the glue is brown, rubbery stuff. Would plain ol' rubber cement be a better choice?

(FWIW, if it's not already in my shed it ain't a-gonna be used. ;) )

I found Aldi double sided tape work well when I moved e-tags between cars.

:D

Oddly enough, I found some Gorilla clear double-sided tape in the shed. That stuff is goood. (Provided that you never want to remove it; then it's a nightmare.)

Just about any silicon will do the job

The Gorilla tape didn't work; applied it about noon then went for a drive just after 4PM and it came unstuck, leaving thick strands behind. The tape melted under the heat of the sun. (30°C-ish) It actually cleaned up really easily while still warm. Hmmm... I must remember that!

I have both neautral cure silastic and rubber cement. I'll try one of those tomorrow.

3M VHB tape

This stuff is strong! Isn't it always the way - I just threw out some 3M automotive double sided tape offcuts that a fellow woodie gave to me several years ago. "I'll never use that!"

He had scrounged them from factories in Thomastown.

Genuine VHB tape is incredible. I have used it on powerboards to stick to vertical surfaces in the shed and Im pulling out power cords and they havent come off! I use it cause its so hard lining up those screw holes at the back of powerboards

I'll second silicone, and you can even buy small toothpaste style tube if you just need a small amount.

The rubber cement (the type to repair shoe-soles, not patch tyres ;) ) didn't work for more than a couple of days. It also failed when the mercury went up.

Once I clean up the residue, Silastic will be the next attempt but I'll need to make wooden braces to hold everything in place while it cures.

(Dammit, I wish I could simply use a bit of fencing wire, duct tape or a 6" nail and call the job done! :~ )

Baling twine fixes everything!
