Darn it, I scratched my Roland Now what

Gare what a bummer: sorry to hear about that, but it happens to most of us sooner or later. If you must try a compound: get POLISHING compound not rubbing compound. Some times a black permanent marker (Sharpie ultra fine tip) or a Marks-a-lot can be used to to fine-touchup small injuries on black surfaces

Dude, you could just chill out. that's my advice. no offense at all because we've all been there but sometimes we all need to chill about this stuff. and sometimes we need someone to remind us. in this case it's me. chill, bruthah.

I've never tried this, but you might be able to use some of that bluing material used on the metal surfaces of firearms. Check with your local gun shop. If the color is close enough, you might be able to apply a tiny amount with a very fine brush just to hide the mark. I've used a regular old black marker before with excellent results. Good luck.

Here's a trick that I've found to work better than black markers for touching up scratches on a matte black painted surface. It does, however, require use of printmakers etching or lithography ink. You can find it in well stocked art supply stores. Dilute the ink to a viscous consistency with mineral spirits & apply with a small touch up brush appropriate to the width of the scratch. I found it matches the finish much better than marker, which is a good touch up for some anodized finishes. Will.

Just contact Jeff and see what he can do for you. I've been there and his customer service and willingness to assist his customers in anyway possible is second to none.
