Hot air gun for 2 min (300*c) + 71mm guitar pick and still won't open
Device is water damaged
The hot air gun is set to 300*c and the glass is almost too hot to touch. However the guitar pick (71mm) still doesn't open it. Are there any better tools to open it (household items please), or am I doing it wrong (I'm opening in the corners)? Thanks!
Is this a good question?
