Thank you for the reply, Bondoking. I was afraid that it is like this. This is really tough! I don't think I would be able to shoot it then, as I am a beginner (painting at home) and I do quite a lot of minor shooting mistakes which need to be corrected by sanding and buffing.
When I shot light gray epoxy, the surface looked really matte and nice. After sanding, it still continued to look nice.
When I shot black 2K primer, the surface looked really bad after sanding. I mean it did not have a uniform matte finish.
But what would happen if one shoots black epoxy? I know that light gray epoxy looks great. But will one get a uniform matte finish with black epoxy, particularly after sanding?
I am asking this because I am running out of time and may not be able to finish painting this year. So I want to shoot something on my car that will protect it against the elements (as I will be driving it), but at the same time wouldn't not look ugly. Then next year, I could get back to painting it. So I thought that black epoxy could do this. But I have no experience with it.
