The SUN "makes" a good /flat paint. For quicker results.... try Sherwin-Williams/Martin-Senour. (Auto paint jobbers...not latex stores) factory packaged colored primer-surfacer. Red-Black-Blue-Green-etc-etc. It's composition is basically some urethane clear ....with pigment.... and talcum powder. It requires its own catalyst- hardener.... so consult your paint store for PROPER safety precautions. The paint stores will also sell quarts-gallons of "FLATENER" that is basically a ton of talcum powder that you add to single stage color. Flatened-clearcoat (catalyzed) is also offered by the manufacturers ....but is somewhat tricky to apply. If you are just flatening a hood, the tinted-primer is quite easy for a do-it-yourselfer. If you are doing an entire vehicle in one session, ...get professional advice beyond my QUICK answer on this column.
Your going to get a bunch of BS answers but the truth is that pretty much any paint can be made flat. There are flatteners you can buy that will matte single stage paints. Also, there are flat and matte clears that can be sprayed over anything pretty much. Some people even run base coat, clear coat paints without the clear applied. They seem to holdup remarkably well in spite of not having any real protection over them. Last option is to use a premade paint product like Hot Rod Flatz brand paints. Some people don’t like them but others have had good results. Shoot us some pics when you get it going.
What color? Also If painting an entire car I recommend 2 painters This helps eliminate streaks in the center of large panels
That's the best approach so you can choose which quality of paint and the amount of flattener will be listed on can so you can get a proper blend if more paint is required.
I've used flattener in single stage. It works in any color even metallic. The only problem is if you have to touch it up it's really hard to match the same amount of "flatness" because you don't really know where your at until it dries.
I dont have any experience with it, but how about Hot Rod Flatz? http://www.tcpglobal.com/Automotive-Paint/Hot-Rod-Flatz/
I used their flat Hot Rod Black on a old coupe and it was chalky, the least little thing would mark it. See the left fender...
With a name like hotrodprimer I can assure toy I have tried many different paints & primers to achieve a non glossy finish, I have always preferred a low maintenance finish with mixed results, it looked good for a while but rain,sun caused fading and after a while it looked bad, then I found Kirker and used it will offer a photo of what worked got me. Kirker Semi-gloss black on my Deuce pickup and will use it again in the future, it holds up in in the weather, it doesn't streak or fade and after 7 years it still looked good when I sold it. HRP
Back when you were driving a car in primer and you wanted it to look good you simply sprayed a new cote of primer. Suede was unbuffed lacquere that might be seen for a week until it was cut and buffed. I don't care for any of it now it's not done until it shines!
