Review: Rich color with great coverage - I restored a horse trailer using this product. This paint is perfect for spray painting a metal surface. Coverage is impressive and no issues with running. The color is rich and as advertised. Spray nozzle is easy to press w/o having a connected handle. Great product
Review: Great product, self leveling - Love this company. My photos are of the dark green color atop the primer. I use it on cast iron and also on this old rusty bench I picked up at the dump. The primer levels pretty freakin smooth. As does the paint enamel. Yes it takes a while to dry, be patient. I’m in the south so I paint it in the evening outside to let it dry overnight, then let it cure in the blasting hot sun all day. It sets hard as a rock. The primer & paint in the can does go a long way, thankfully, and didn’t get clogged. Nice even spray. Adhesion was fantastic. Everything I repainted was either an antique or rusty, and while I did spray the metal with the power washer before hand to remove loose old paint chips & dirt, but I didn’t sand smooth or anything like that. I don’t mind texture on antique cast iron. My intention for buying this paint was protection & durability. And this company provides both of those things. I really am enjoying the dark green paint color. It dries a little darker than when initially wet. Both pictures I posted are the same dark green color, the bench is in direct sun, the porch posts I’m making into an arbor is in the shade when I took the photo. It is lively, elegant, and to me has more appeal than black- Especially on outdoor metal
