Cleaning Up Sanding Marks from A Mediocre Ding Repair?

General Discussion
1

I got a hold of a used board recently and want to do some esthetic clean-up.  It has a couple ding repairs where the gloss coat in the surrounding area has either been scratched up with what looks like 120 grit sandpaper, or looks to be mostly gone.  Standard poly board.

How should I go about remedying this?  Apply fresh coat of resin with sanding additive mixed in, and then polish to taste?  Will I be able to blend this with the surrounding areas?

Or should I attempt to polish what remains there with some form of polisher, like this:  http://www.foamez.com/surfboard-polish-quart-p-664.html

Thanks -

Or maybe just this stuff?  The scratches are more than a swirl, but if I can just get back some luster in the area I'll be happy.  One of the areas is not down to the weave, but the other is pretty close.

I have some Solarez resin sitting in the garage.  If I add sanding additive to that, can I safely use it as a gloss coat?

If glass cloth is not showing, you might try to sand lightly with higher and higher grits, like 220, 320, 400, 600, then polish. Otherwise, I would mask off the area, brush on some gloss resin, let it cure, then hit it with whatever grit will be needed to feather it into the original gloss, then 320, 400, 600, polish.

   Howzit noleash, What you haveto be careful of is sanding through the gloss around the areawhich happens a lot when trying to clean up the gloss on a repair. Try spraying a few coats of lacquer making sure each coat dries before appling the next coat. Lacquer will buffout like gloss resin and will fill the scratches .After sprayig start with 400 and then 600 then rubbing compound. Use a good quality lacquer since it will get nice and hard and use a light touch. Aloha,Kokua

Thanks for the tips, Balsa and Kokua.

I had round 1 with automotive polishing compound and a random orbital buffer.  Took out the top 70-80% of the scratches and put a crazy polish on the board.  Still some stuff left, and may hit it with lacquer next.
