Answer is absolutely. I like to remove my shutters and clean and spray them with color of choice (2-3 thin coats). If shutters have to remain on house depending on skill level whether to spray them or not.If you cant spray,brush them (2 even coats). Remember to apply lite pressure to brush. Only insert your brush 1"inch into the paint to help contain mess.
Do not hesitate to use spray can paint for this app.Again multiply lite coats. For product recommendation please email me.
