If you have a small detail gun you can get a pretty much non marr-able flattened paint. grab the paint you want that is the color match to you other black. pour a bit into the mixing cup and add talcum powder.(yup baby powder.) Just a bit since you won't need much. mix that batch and test add more or less powder til you get a non reflective mat finish. I added 1 teaspoon to 4oz of clear to finish off my dash top
before
masking for final
after shooting flattened clear and yes if it scratched you can sand it to get rid of the scratched unlike flat or satin black.
