as an experienced painter, that sounds definately like orange peel. As long as there is enough clear on the car you can try to wet sand with 1500 grit and buff it out. But if your not experienced in it, I wouldn't try it, otherwise you'll be getting a new paint job. If you sand too much, you'll take all the clear off and go down to the basecoat. If you buff to much in one sand, it will literally burn the clearcoat. Also if the dimples as you call them, are real bad, sometimes that comes from poor body work, they are called fish-eyes. Its where there was a contaminate on the primer/basecoat. Like someone that used a lot of tire shine and didnt sand the car down that well. If they are little spots that look like craters, then thats fish eyes, if it looks simple like an orange peel, then you can wet sand and buff them out... but like I said, be careful!!!! When you buff it out, use 3M products. Ask a parts pro for help.
