dull smudges on clearcoat
 

I just got my car back from the dealer's body shop after having to take it back once already for shoddy paint work. They keep leaving these dull smudges on my clearcoat! I'm so sick of taking my car back to those sloppy M-therFockers. Does anyone know of a solution to this dull areas on clearcoat problem?

Clay... Meguiers makes a very good kit. Its for sale on their web site.

thanks.

Clay is for removing embedded dust and particles, like the fine sand that builds up on the surface that you can feel with your hand, and just won't come off with microfiber cloths alone. Some of them can be picked off with a fingernail, so clay is used to sand them down, chop them off, shear them down, bit by bit.

What you've got, I think, is a poor polishing job done. That happened to me after a dealer paint job, where there were areas left that appeared "porous" and "rough" and some areas "scratched looking" and small areas with "booger" shaped foreign matter trapped beneath. And the hood where they apparently let a powertool rest. Well I can only imagine dull areas happening if they did the polishing in a dimly lit garage and didn't have an adequate light source... really, really crappy job. I took it back once, and they got most of it out, but it wasn't worth going back again to keep thinning the clearcoat more and more.

I've learned that if the car has to be painted, to never go to a Mazda dealership, but rather one that services more expensive vehicles. For a rear bumper replacement, where the new unpainted bumper will be painted, but no paint needs to blend onto the existing car, a dealership will do. Anything more that requires original paint to be blended simply requires too much skill for a dealership to handle.

To correct, I would need to get into buffer tools.... porter cable, rotary buffer, orbital buffer, stuff like that, that I do not want to get into.
