I use double side tape for carpet. :lol:

Maybe hot glue, it's kinda messy though.

In what way "didn't" work? Fail to stick?, pull the paint off?, something else?

... and not a good idea due Lexan being a thermoplastic, and hot glue being, you know, hot? ;)

Hmm... I recall someone having fixed the F40 shell I have with the stuff.
Must be another substance then. Haven't ever used it myself actually.

:whistle:

Not an option to put it on the magnets, let it cool a bit and then apply? How hot is it practically...

As Lexan® and Ultem® are isotropic and amorphous polymers, they are relative dimensionally stable at high temperatures. Short-timed tests (30 min) in the laboratory did not show noticeable changes of measurement. Lexan® was tested up to 135°C and Ultem® up to 150°C. Lexan® films with a thickness of 0.075 up to 0.125mm shrink about 0.5% at 150°C (glass temperature). Thicker qualities shrink about 1% to 2% at the same temperature. At temperatures above 150°C the shrinking increases clearly.

No idea about other makes/models, but there's a warning label on mine (a 2003 Arrow Electro-matic TR550) says the glue & nozzle reach 196 Celcius.

They apparently come in high (170-195) and low (75-130) temperature versions...

It probably wasn't the greatest general recommendation though.

I used hot glue on several lexan shells to install lights and to keep the wires in place no problems so far.
