That it’s melamine changes my thinking. Looks like a hot nail but guess it’s not.
Gonna change my mind to stain or burn.

I agree about cutting away the drywall. Easy to fix after, especially since inside a cupboard. I would avoid touching with metal and wear insulated gloves I think.

I’d like to be able to easily play music stored on my devices (phones, tablets, PCs, Nas) over the stereo system I own, anytime, controlling it with said devices, without having to manually go through multiple setup steps to get everything powered up and paired every damn time. Is it possible to get it all set up once so that I can simply hit play on my phone and hear the music whenever? Seems like it should be doable but I haven’t been able to figure out how to get it done without having to go through a whole rigmarole every damn time. 😄 Would really appreciate any answers or leads.
