One of the Best Spray Paints
I've used MRO flat black and yellow paints and I've been impressed so far. The paint coverage is excellent. After 2-3 coats you have a good looking and durable finish. It does take a surprisingly long time to cure, however. It dries to the touch in a couple of hours, but the finish is still pretty soft and will scratch easily for a day or more. I would err on the side of giving it a weak to cure before putting it through any hard use. I attempted to bake cure in a dehydrator (sub 200 degree F temperature), but that results in wrinkles in the finish, so I do not recommend that. I swear that the yellow has a hint of banana smell Overall, the paint works well.

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

Good quality
Good quality. You can polish this paint so it's shiny and reflective like a mirror.

Good paint
This Seymour MRO is good paint, it's not as spectacular as i was expecting it to be. Coverage is good but not excellent, better than a rustoleum industrial can though. The finish is smooth and is really helped by some polish after it fully cures. The worst part about this can is the spray tip, it sprays a decent fan, but is stiff and uncomfortable as all heck. Swapping tips or using one of those 'paint gun' type attachments may be a decent idea. I'm happy overall with this paint, it did what I wanted it to do and the color is exactly what I wanted. (In my picture the 'grit' in the dimples is intentional and has nothing to do with the Seymour paint)

Automotive paint
I bought this paint to spray paint my vehicle myself but was quite a challenge though as you really need an attachment that makes the paint spray finely. It’s good automotive paint but you gotta know what you are doing so you don’t mess up your vehicle.

Good Coverage
For some reason I decided to clean up and repaint my old 5-inch vise. I chose the Seymour MRO High Solids for several reasons - resistance to most automotive chemicals, solids to fill in the multitude of dings, and one coat abrasion resistance coverage. After wearing out a couple of wire brushes cleaning it up, I used an engine paint primer then sprayed the Seymour. Coverage was very good, and despite the numerous curves and crannies on the vise I had no issues with drips or sags. The paint dried glossy, as expected, but I did find the color was a shade or two lighter than the dark grey represented by the can's cap. Not a big deal, but not my idea of "dark" grey. I did have an occasion to contact Seymour's customer service for some tech support. The rep I talked to was very helpful and pleasant to deal with. Time will tell as to how well the paint holds up, but it certainly looks good right now. It might stay that way for a while, because after all of the work I am reluctant to go beating on it.

What?!
I usually try not to write bad reviews about products unless the customer service sucks or the product sucks. For this one it's the latter. Let me start off by saying I've been rattle canning for a while. I got plenty of painted projects I've done with rattle cans. I tried this brand because it has tons of great reviews; plus, the end result looks amazing. I unfortunately did not have the same experience. So I made sure to follow all the directions. I even have a rattle can machine that shakes my cans for me. After spraying the primer, I expected this stuff to be about the same spray pattern as the same branded primer. That was a fail... Once I started laying down some paint, I started thinking my pointer finger was getting tired. I could barely press the sprayer. I realized it wasn't me. It was the freakin sprayer. Even finger lifting champion couldn't press that nozzle down for extended periods of time. I tried my best but it came out terrible. I was getting drips of paint on my project and the spray pattern itself was super narrow. I must have gotten a bad batch but man was I disappointed. I'm literally writing this as the paint is drying. That's how mad I am about this stuff. Hopefully everyone else has better luck but I'm sticking with other brands from now on....
