etchimg primer should only be used on bare metal if at all. i would use epoxy instead. if the black coating will pass these tests i leave it on. laqure will not remove it and if it will feather nicely. if not strip it off. the instructions from the panel manufacturer that i use is to rough it and prime over it.
