L. My car, a 2004 Mustang, has always been kept clean except to me that meant running it through a drive thru carwash with brushes. He's going to get rid of the light scratches, fix a couple of door dings, clean the convertible top, fill in a couple paint voids (chips) with paint and buff or sand that out and get rid of some overspray orange peel by wet sanding. It is an exterior detail only, and he said he'd take a look at the wheels, but no promises. I have a lot of little tar stuff on there. Maybe a couple of other minor things and it's $200.00.
For all that is going to get done this is very very low.
The thing that worries me is the wet sanding. Its known that factory clear is very very thin to begin with. Its usually no thicker tan a sheet of sticky note paper (Thats Thin)!!
Not only that but typical paint thickness (overall) is usually 3.0 mils and that too is thin. Along with the danger of thin paint on a new car there is a greater chance of the paint being even more then on an older vehicle that might have been polished out before which will reduce the thickness of the paint even more.
When wet sanding a factory paint you can safely remove up .5 mils and that about it.(not very much at all) Anymore then you run the high risk of burn through which would then require a repaint of that panel. With orange peel on a factory paint job its best to learn to live with it and keep it looking its best.
If I were you I would do some question asking. Anyone with knowledge that does wet sanding will have a paint thickness gauge on hand and will take measurements before doing any work at that level. I would ask if such tool is available by the the detailer and if he can take measurements of you paint. A healthy factory paint should show in the range of 3.0-4.0 mils some times a little bit higher but not much.
Additionally find out about tools, products, and process. The detailer should be using the least aggressive method and not just jumping with with a rotary and wool pad (unless recommend and enough paint is there to do so). If such aggressive combo is needed find out what steps are taken after that like the finishing process like foam finishing pads and a polish to remove and holograms that might have been inflicted into the paint from a rotary, wool pad, and compound.
Knowing some of these finer details will been help you decide if this is the person you want touching your precious car and performing the work.
When dealing with work like that at that price I would be very cautious. Its ok to decline the service should you not feel comfortable.
What is you location? There might be a member here who might be able to assist you in having your vehicle done properly if you need it.
Hope I have been some help.
