My son just bought a used car which has an antenna mount for a
satellite radio stuck on the outside of the rear window.

It's a lump about 1-1/2" square with a short male threaded antenna
starter piece sticking out of it.

He's no intention of getting a satellite radio and asked me how to
safely remove that piece.

There's a matching lump on the inside of the glass which I assume is
inductively or capacitively coupled to the outside piece, but he's not
much concerned with that one and if it happens to be stuck over one of
the defroster grid lines he's better off not messing wwith it.

I presume the outside piece he wants to remove is adhesively attached
to the glass and wondered if the folks here here can recommend a safe
way of removing it without risking damage to the rear window.

Thanks guys,

Jeff

it's probably some sort of epoxy or uv glue. if you can take the window out
and stick it in an oven, it'll release around 350F.

there's a product called Attack that will dissolve epoxy, but you have to
get it to stay on there for a couple of days or so because there's not much
glue surface area it can get to.

i doubt a razor knife will touch it. the glue may be stronger than the
glass.
