So im looking for some advice on how to paint a pre-powdercoated enclosure. I have a TEB setup that i just finished cutting the holes in, and in doing so caused some damage. There are a few decent scratches and scrapes on it so id like to give it a new coat of paint. IF anyone has any advice id love to hear it, id rather not paint this thing incorrectly and then have the paint peeling off once i get everything installed.
Points of consideration.
Do i need to wash it? i had to use a good amount of cutting oil at times, and im sure there is a residue?
Paint prep? Do i need to sand it down, fill int he scratches or will a decent paint fill them in?
Primer? Do i need to prime it if its been powder coated?
Is it even possible for paint to adhere to powder coats?
I was thinking of a good automotive spray would be the way to go. Other opinions are welcome.
