scratch on side of adcom best way to fix

I agree with Albert, Sharpie is the best, and often works wonders. I've picked up some pretty rough equipment used and have tried other options too. For gouges in paint that hit bare metal and can't be covered with a sharpie, you can touch them up with Testor model paint available at a hobby shop of craft store. The paint comes in 1 oz bottles - flat, semigloss, or gloss. You also need a fine tip model brush. Recognize that this will cover a scratch that's visible from a distance, but is likely to be noticable close up, and depending on your workmanship, it may look worse than the scratch.

Black markers have worked fine for me. The side is not as bad as the face but the person above is right. The cost though is more than what the scratch will cost you on resale which isn't much.

Hi
A lot of people just use black permanent marker to touch up scratches on painted metal.Aluminum is another story.I understand your Adcom side panel is sheet metal sprayed in black at factory,so you could use a black marker.If you want the best then you can fill the scratch with layers of paint,you have to mask around it and keep applying the paint in layers once the previous layer has dried out,put another and so forth.Look at the automotive section of a hardware store for a touch up paint in small bottles.The cover has a tiny brush on the inside.You can get a good result like that.At the end you can buff it up with polishing compound.
You can always remove the panel and send it to be sprayed in a auto body place.
Best of luck

The safest thing to try on a painted or anodized black cover is a Sanford Sharpie.

A Sharpie is basically a laundry marker with durable ink. I've had amazing success, particularly with the "Ultra Fine Point" version.

The good news, if it looks worse after you make the repair I can be removed with a little effort.

The Sharpie cannot fill a deep scratch, one that is down to the metal but the only way to make that kind of damage like new is to refinish completely. I'll be surprised if the Sharpie doesn’t make it all but invisible and it’s almost no cost, no risk.
