We are replacing all 22 of our interior doors with 6 panel doors. I plan on buying doors that are primed and ready for paint. Wife wants black doors. I believe spray painting would yield the best results as opposed to brush. Spraying will be faster and, if done correctly, look better. I only have spray equipment for thinner finishes. Based on spray painting with latex water based paint, what would you recommend I purchase. I've had experience many (+30 years) years ago with the Wagner 220 which did a good job on rough surfaces and split rails, but did not perform very well on smooth surfaces. So I'm looking for advice on latex sprayers that do well with smooth flat surfaces. Does Wagner make a better gun now? Advice and opinions needed on quality latex spray systems.
