My husband has a professional paint sprayer. He paints cars.
I have a Wagner. It works great, but you have to be careful with it. If you paint outside on a windy day, paint travels. You get overspray everywhere.
Be sure to stay away from your house and car and cover the ground if you paint on your deck or sidewalk or concrete driveway windy day or not.
Sometimes I just use a paint brush. I only paint when the wind is calm. It is fun to use if you're careful and take precautions.
