If you would like to use automotive paint on wood cabinetry, there are a pair of important factors you will need to consider. First, regardless of what type of paint you choose to coat wood cabinetry, you must condition the surface to accept adhesion by coating it with an acrylic latex primer, or the finish will peel soon after application. In addition, because automotive paint is relatively thin and runny, you must use a specific application strategy, or you will see runs and sagging in the final finish.
Remove the shiny varnish topcoat from the wood cabinetry by sanding it with sandpaper. Skip this step if the wood is unvarnished.
Wipe down the wood cabinetry with a tack cloth.
Cover portions of the wood cabinetry you want left unpainted with painter's tape. Protect flooring below and adjacent to the wood cabinetry by covering it with plastic drop cloths. Lay fabric drop cloths on top of the plastic ones.
Pour one gallon of acrylic latex bonding primer into the two-gallon painter's pot. Apply a coat of primer to the wood cabinetry using a two- to four-inch latex paintbrush. Allow the primer to dry for three hours.
Wash the brush with water.
Pour one gallon of automotive paint into a five-gallon bucket.
Apply three light coats of automotive paint using the two- to four-inch latex paintbrush. Do not over-apply. Smooth any runs with the paintbrush as you apply. Allow two hours of dry time between coats.
