Finish quality has a lot more to do with good prep and patience than it does with high-quality paint. And you don't even have to be that patient, or talented, really.
To sum it up, If you clean the surface well, and use a few coats of primer before the matte black, you stand a good chance of making something indistinguishable from pro-level work. If you still have the patience to clear-coat it afterward, you'll quadruple it's lifetime.
Step 1, Cleaning)
This can be done with a brillo pad and some IPA
Step 2, Primer)
Prime. After the second coat dries, take some 220 sandpaper to any areas that show texture. Repeat until you're satisfied.
Step 3, Raise bond energy)
Lightly sand with 600 grit or finer, for just a minute or so. This is important. It mechanically breaks the bonds on the surface of your primed part and 'readies' the primer to accept paint. Quickly wipe down with a brand new clean rag with a little bit of IPA on it, and immediately again with the dry side of the rag.
Step 4, Paint)
Paint that sucker within 2 hours of step 3 (or skip step 3 all together because the bonds re-link if you wait longer than that). Flat black acrylic spraypaint will look just fine. If you fuck it up and it texturizes, wait for it to dry and go back to the sanding part of step 2.
Optional step 5, Clear Coat)
Start at step 3, and do step 4 with a UV-resistant clear coat instead of flat black.
Thank you! This is exactly what I was looking for. Will post some pics if I end up doing it.
