I just had new porch posts installed and since the weather is getting nicer, I need to paint them because their natural color is an off white/yellow and they look horrible. They are a resin composite and the manufacturer suggested a "high quality" acrylic (latex) primer and then whatever exterior paint you want. I usually just get Behr or something middle of the road but a lot of people have recommended Benjamin Moore fresh start primer and then their Exterior latex. I am overwhelmed by the options. Any painters here want to weight in?
