Kirker solid colors can be color sanded to remove orange peel. Start with 600 wet. Move up to 800 wet then use a medium compound on a wool pad and buff to a sheen. Move to fine compound with a sponge pad. If you have swirls in the finish use a swirl remover compound with a sponge pad.

This will only work on "solid" colors, NOT metallics.

Another method: If you want the finish to be glossy, you can sand the orange peel out with 360 wet, then apply a 3 coats of clear. Use a slow (high temperature) activator and reduce it with slow( high temperature) reducer. The slow activator and reducer will allow the clear to "flow out" smooth. But you have to apply it in thin coats or you will get runs or sags. Put the first coat on lightly with a little gloss, the second and third coats heavier.

remember: painting clear is a controlled run. Meaning that you put on the clear until just before it starts to run.

and the down side will be if and when you sand thru to the primer and have to paint it again.

Or I would think (I don't know this brand at all) you could sand it with 600 and apply a "Matte" clear which will retain your "Flat black" look with little gloss.

The hotrod black he speaks us is supposed to give you the "RatRod" look (UA-70388 Hot Rod Black (Satin Finish) ).. Flat, semi gloss, satin, whatever you want to call it, you dont want to sand and buff as this will bring up more shine than what the product is desinged to do.. If you are wanting a bc/cc look, then that is the wrong product for the job..

i would sand it with 320,400,600 or even 1000 if you dont like the more aggressive grits and then re coat it.. This will be just like flowcoating a clear coat.. It will lay out smoother the second painting, but gun adjustment is the key to getting your paint to lay out as smooth as you can..
Check this out for your gun adjustment.. This applys from epoxy to clear

Proper Gun adjustment

Here is the link for the product as well

If he sands out the orange peel, the surface will become duller or flater. The buffing will remove the sanding scratches, but the surface will still be satin. That's the nature of this paint.

You can still add a several coats of satin finish clear to give it a more durable finish.

Clears are normally thick in nature and tend to clump when sprayed heavily or with a too high a fluid setting on the gun. More pressure, and a thinner fluid setting can help alleviate the orange peel affect. However, reducing the clear and slowing the "setting" speed also helps trmendously.

And with some of the "cheaper" guns this is the only way you can prevent orange peel. How do I know this? I started with the Cheaper guns myself. Still have some. They just don't have the adjustment available to accomodate the heavier paints such as high solids clears.

And how many people use just the tip that came on the gun? Most do. So the solution is, slow your activator and reduce your clear.
