PLA on spray paint

Has anybody tried spray paint your removable bed glass or what ever else you have on top of heat bed ?
I did and i love it.
Works even better then hair gel.
Printing small parts heat bed at 50 holds it firm enough and i dont have to wait for cool down to remove it.
For bigger parts i would have to heat it up more, maybe up to 80 and IF going fast print. Otherwise 50 is just fine

Try it, works awesome.
I use cheapest pain from homedepot called Quick color.
