How do I paint a refrigerator?

Appliance Spray Paint.

I would use a black spray paint. Do multiple light coats. Protect the flooring and walls around it to catch spray drift. Be sure door seals are well masked and remove handles before painting so you don't have cream showing.

Also looking into stainless steel paint

I purchased a stainless steel kit off of Amazon, I have yet to use it, but I got high reviews.

Depending on the surface of the refrigerator - I would sand, clean and prime with XIM bonding primer two coats, then paint a product called Bondago it is a primer/paint and comes in Black - then top coat in BenMoore StaysClear - here is a link to the Bondago: https://shop.artisticpaintingstudio.com/products/bondago
