How do I check for an inferior auto paint repair?

I am getting a scratch on my car repaired. They had to sand down the area and repaint it. How will I know if the repair or the paint job that has been done is inferior? I want to be able to know enough to refuse the work and/or request that it be redone properly. Please help!!How do I check for an inferior auto paint repair?
when you get the car back take a look at the spot they did work on





look very closely from all angles





feel on it for bumps





if you see bumps, high or low spots, or even color mismatch then you can refuse the work and request a do-over.





the bumps are caused by inferior prep work and failure to keep the area clean before they apply primer or paint





high or low spots are when the area that has been repaired appears to be higher or lower than other areas, this comes from use of too much or too little coats of primer or paint





well color mismatch is obvious if the color doesn't match then don't pay for it (and don't let them tell you it will get darker the more time it has to dry this is a trade lie) they should never try to return a car to you that has not had the proper time to dryHow do I check for an inferior auto paint repair?
If you can't figger out where the scratch WAS, then it is a good match paint repair...
I agree with whomever said to look at the area from all angles. Look down the side where it was preferably in bright sunlight. If you see swirls, they've damaged more paint. And look for what body shop people call ';orange peel';. If the paint is looking like the texture of an orange peel, then that's a very shoddy paint job. And while you're in the sun, you'll be able to tell if the paint was an exact match. A good body shop will redo the job if you politely complain.
You never know until it's done. If they took the care to poperly blend it to the exisiting paint then they most likely did a quality job.
1. Check color match by looking at repair area vs. other panels on that side of car.





2. Look for sanding or grinder indications that may show up through the paint. If you can see any small scratches, or can see imperfections easily, it's bad.





3. Runs, small bubbles, pitting, etc... all bad.





4. Finish - is it shiny?
