How to fix scratch on hi gloss Velodyne sub ??

If the finish is a lacquer, you can fill the scratch with new lacquer and use ultra-fine abrasives to level the new lacquer with the old.

If the finish is a catalyzed polymer (I suspect it is), it's not possible to do this. Catalyzed polymer finishes will show a repair attempt unless the finish is removed and the entire piece is refinished.

One thing you might try, if the scratch is shallow, is using a high-grade automotive on the surface where the scratch is. It won't fix the scratch, but it may make the reflectivity of the surface uniform enough to disguise the scratch from casual observation.

Sorry, that should have ben "high-grade automotive WAX."

If the above suggestions fail - you could go to a local glass store and get a piece of black mirror cut. They have a variety of edges they can put on it for you. This would leave you with a beautiful high gloss black finish. Good luck on the above procedures. Experience has shown me it usually gets worse the more I try to do.

Look in the Yellow pages for a piano refinisher and see if they can help, I agree with jjmali everytime I try myself the repair becomes the focal point ,good luck John
