Eastwood makes some good coatings for natural finish looks $$$. One really good paint I have used is sold at Home Depot(Rust-Oleum)it is an enamel for refinishing appliances. It is about $5.00 a can and if you let it dry overnight after spraying and follow-up with another coat it is very tough and durable. I have used both the black and the white and they are both good.
