Black sprayable primer from Advance is a real close match color wise and not too bad on the texture side. What I don't know is how it will hold up to sunlight, I used on the behind the bumper area on my AAR, if was tough to tell where the organosol stopped and the primer started, been on for 6 months on so with out fade.

I tried to post a picture but it was too big, PM and I will send them to you.
