  • Removing sandpaper scratches from finish?

    Posted by Casey Guitar Repair on September 10, 2023 at 3:23 am

    Had a rough day yesterday and spilt some water thin glue onto the left shoulder of a Martin HD28 and repairing it just dug me into a deeper hole.

    I removed the glue but left some ugly sandpaper scratches. I’ve used a lower grit than was needed in the panic of it all.

    I’m not very experienced with finishing, polishing etc so will take it to someone who is to be on the safe side.

    Could anyone tell me what the process is for removing deep sandpaper scratches for future reference and what I should expect the job to be

    Thanks

    What grit did you abrade the finish with? Without that info there isn’t much guidance to give.

    If this is a gloss nitro finish, you’ll need to abrade it to 1000 grit or higher to buff back to a high gloss.

    If you abraded with 220, that’s a long slog to get back to high gloss and on a thin nitro finish, easy to cut through the lacquer.

    Let us know what grit you abraded with.

    It may be tough to do, but if you could post a pic, it would really help This is a safe space for this kind of thing.

    It’s bound to happen to each of us sooner or later. Part of the journey unfortunately. I spritzed a new D28 will lacquer thinner once by cleaning my tools near my work area. I would’ve given anything for this community back then, so yes please post pictures.
