I'm unbelievably happy with the end result.
Went on very smoothly, took 3 coats.
A lil bit managed to seep through any gaps in the masking tape but I scraped it off and washed it down.
I actually sprayed the wrong side (because I'm an idiot), I thought I wouldn't be able to read the thermometer but I was just imagining things.
Sooo yeah... Blackboard paint is the way to go.
