Dirty lens? What the heck is this?
recently at certain lighting I would get these weird green dots... Any clue? Is it my lens or camera?
Nikon D50 w/ 18-55mm or 70-300mm... I think they all came from the 18-55mm... I checked the lens and it "looks" clean to "me"... help?

cool, thanks!
I need the sun's reflection... that's how it shows the correction has been done... if it hasn't been correction, you'll see all the crazy swirl marks surrounding the sun's reflection. Thanks!

circular polarizer anyone? It'll drop your exposure by two stops, but it should take care of the lens flare, or at least minimize it.
Perhaps you can try lighting it with an off-camera flash unit attached to a tripod, and perhaps a small softbox for the flash (or diffuser)?
I don't think the sun is your best choice for your sensor.
You might be well served finding a shady spot to shoot, control your lighting, and make sure the sun isn't in the image.

i've tried the circular polarizer, but sometime it would give me funky color... this one is actually a better one...
and i really need the sun's reflection so it would show paints imperfections like these... and of course, after correction, to show these imperfections gone...

Yeah its lens flare and a cpl(circular polarizer thats adjustable) wont always get rid of it(and can make it worse). Your UV filter is most likely actually causing it or making it worse, and on top of that if you stack a cpl on it chances are youll get vignetting. I would get a hood and a good quality cpl and ditch the uv filter unless your shooting a event or something where your lens is in harms way. For a auto shoot its pretty safe to just rock a hood. As far as your polarizer causing funky colors its most likely from being a cheap filter. Make sure you buy a name brand cpl and not a fixed polarized filter.
