wow, for that price it seems to me you could and should have gotten a better outcome or gone to a better shop. Ive heard sooo many horror stories about macco. The only way I would have them paint a car is if its one I just didnt care about and only wanted one the same color overall. Not only does it look bad now, Macco paint jobs are notorious for looking like crap in only a few short years. But ok, too late to worry about that right now.
The first action to take is to let them try to make it right. WRITE down all the problem areas you see and want fixed. Then make an appointment with the shop foreman and discuss everything over the car. Using the written out list of things you want fixed, have the shop foreman Initial EVERY single line item of what you want done, and sign the bottom of the sheet. If he agrees to this let them try to fix it.Give them ample opportunity to fix the issues.
If on the second attempt you are unhappy, you should contact several new shops and get estimates for repairing the paint job. Contact a lawyer and have his office draft a letter to macco stating that you are unhappy with the work and have several estimates from other reputable shops that you prefer do the work at this time. Give Macco two options, refund the amount it will take to get the new shop to fix it or take a 3rd crack at getting it right. My guess is that in the face of legal action and the cost of dealing with that, that the Foreman will put his best guys on the job and probably get it right, or at least to your satisfaction. If not you may have to sue for a partial refund.
In all honestly, you may be stuck with what you got, but I would fight for what you wanted and paid good money for.
