Old topic, but I add my own work here.
Not Package Tray Paint, but maybe the same output. I used Eastwood Trunk Paint Aerosol. Just very thin single layer. (I tried this for the trunk, but it was not good enough for that purpose). The pattern is very low and therefore it did not fit to the trunk paint so good.
When it was dry, I painted basic matte black on top of it.
I think the result is acceptable. What do you guys think?
Too much texture. Use SEM Texture Coating, have your jobber mix up the paint using the code which has the correct texture additive, or duplicate using dry spray technique.
