I need some options acrylic enamel , sand clear, or just leave alone

ok so i just painted my firewall, inner wheel wells , under hood and dash with acrylic enamel. Looking at the tech sheet it just says 16 hours to cut and polish............ the paint is Omni. the color is pepper gray, would this be considered a heavy mettalic? would this paint mottle if i should sand it ? Since its underhood and all i can leave it alone , i just would like to know my options. Thanks all i be waiting for your responses.

First off 16 hours is not enough time for the paint to cure and if it is a metallic single stage color and you wetsand it then it will have streaks when you polish it if you plan to wetsand and buff then you need to clear coat

I'd wait a week for enamel, and that's if you used a hardener with it.
without a hardener (activator) it may never get hard enough.
Another option is to sand it smooth and shoot another reduced
coat of enamel over it, a flowcoat.
It always flows and lays better the second time.

You can NOT sand SS metalic paint at all ,you'll expose the metalics and it'll stick out like a sore thumb...
However,you can sand and buff ss solid colors.
Anything with metalics should be BC/CC
If it needs redoing you should dust on some base then clear you'll be much happier with the results....Omini wont get you there.
You've gone the extra mile to do a nice job on your car dont stumble on the finish line...

^ Im with you. Especially considering (from the pictures anyways) it looks like it is either really really dry, or you had a flatting agent put in?

In which case ,it would have been cheaper AND faster to use BC/CC to start with...
Omini also makes a cheap base that you can use for jambs and such but do yourself a favor use a good quality base on the exterior and a good clear.
The cheap stuff is way harder for a beginer to make look good.

Yes i will be using a bc/cc for the exterior. Im going to leave it alone. It looks ok , like i said under the hood , door jambs, wheel housings and inner fenders. I allways search here before i post a question, however, i read some post that if it is a heavy mettalic , dont sand it at all . I also read that anything can be sanded, for what that means ,,,,,,, im not sure....I did use a hardner 8:1:1. Like i said i just wanted to know my options on this matter. For a first time shooting paint this much, with a new gun , i believe i did well, but i want to be better, so i need to know all my options.

SS "metallic" cant be sanded and buffed without messing it up .....
SS "solid colors" CAN be sanded and buffed.
ALL SS Paints can be cleared(if sanded of scuffed).for a better shine but you wont get the "POP" a good base does.
The reason is :a base dries fast so the metallics stand up.
SS dries slower, so the metallics lay down in the wet paint and don't reflect the light as well.
SS metallics have the clearalready mixed in them, if you sand it, the metallics are exposed.
With a BC/CC, the clear is sanded so the metallics arn't touched.
If it looks good to you, move on,don't worry about it.
If you want more shine but don't want to start all over again scuff with a "GRAY" scotch brite clean with a wax & grease remover spray an adhesion promoter (like 222 or bulldog)then clear.That'll give you a much better gloss.

I do have the bulldog ap, i was going to use it on my urethane bumper before i shoot the bc/cc. I guess i was just lazy so my thoughts were just shoot acrylic enamel since it pretty much is out of sight, ( until i open the hood ) but im sure most eyes will be on the engine hopefully, lol. Im happy with the results, i can live with it . It has been a marathon building this car , and you are right , dont rush now , im just wanting to sprint to the finish line , lol. Alot of my questions have been answered through previous post . When i was painting i was thinking about the phrase ( laying down the metalics) i want to say i kinda get it now what that means, i just dont have the right words to apply my thoughts on it . ( need more hands on ) . I again want to thank you and everyone else for the input i received.

Doing this stuff every day is kinda easy ...putting it into words is a much bigger challenge for a grunt like me.
