I was working at my workbench using some Acetone and the small bottle fell over and splashed some one me - on my clothing mainly and a little on my wrist.
No big drama - it evaporated away and I had old clothing on.
This morning I tried to push a button in on my resin cased Casio I normally wear.
It wouldn't budge.
I took the watch off and turned it over - underneath the button the case had melted:undecided: Thankfully it hadn't damaged the front.
The button was welded in place.
I thought I could take the back off and remove it etc....but I didn't have to - poking with my fine oiler got it working again thankfully
