[AT] paint question

[jtchall at nc.rr.com]

Got a couple items I need to paint, nothing fancy as I will brush both of them. They are a sprayer frame I am building, and the chassis/frame of a nitrogen tank trailer.

I THINK the paint we used to buy for tractors was acrylic enamel. The Magic brand paint that Tractor Supply sells and the Rust-Oleum that Lowes sells are oil based enamels. How good are these paints? I looked at Por-15 and was turned off by the price.

Opinions?
