Sheet metal, engine components, rims, radiators, generators or starters are often painted separately. In the case of sheet metal the best tact to use is to hang the pieces from the ceiling using wire. Begin spraying the undersides of the metal first. With engin e components that are painted a different color than th e tractor, spray the component first and then cover them before coating the tractor. It's a good idea to have the metal warmed up to 70 F. before painting.
Paint adheres better to warm metal, and provides a better finish.

And plan on applying two to three coats when using acrylic enamel and three to five coats with lacquer.
