So I got a pretty good 3-4 cm scratch (deep enough that finger nails would get caught in) on my new car a couple of days ago and decided to try my hands at wet sanding with the Turtle Wax Scratch Repair Kit. Anyway, in my overzealous attempt at perfection (should have stopped after first round), I over wet-sanded the area, so that I now have a lighter colored blemish around the scratch itself. I'm guessing I went into the clear coat and any additional wet sanding attempt will simply enlarge the blemish. My question is mainly, should I leave it as is (with the cloudy blemish around the scratch, is there any possible future damage, i.e. oxidation, etc?) or should I just apply touch up paint to the entire area and leave it at that? The scratch is completely gone, now the blemish remains.

Here's a closeup of the area. Ignore the horizontal line below the blemish, that's just a reflection. Again, it's all smooth and consistent throughout (even before I put wax back on). The scratch itself is filled.

Not much you can really do... you can try to buff it out with a good buffer and a product like maguires but I doubt that will come out if you went into the clear coat... you should have tried to buff it out right off the get go it's a lot easier on the clearcoat than sanding. Looks like you went right through the clearcoat. Touch up paint over an area that big will look terrible.

get some clear coat touch up and it should fix that
