Being a bit thicker than milk, it can be rolled, sprayed or brushed on. To spray i.e. chassis or rafters we find that an electrical sprayer, not producing the fine spray of a “panel beater” gun, works really well. The electrical sprayer is easy to clean, provides a good, rich coat of paint and produces less overspray. Make sure to shake or stir the paint really well prior to using it ! The goodies are on the bottom!
