I recently purchased an '05 G35 Sedan: diamond graphite, graphite interior, prem package, aero kit, 6MT. After I purchased the car before I left the lot, I noticed a few hairline scratches on the driver door as well as one on the left corner of the front bumper. They said to just go home as the detailers were gone for the day. I went back in the next day, and they tried to buff it out. This accomplished almost nothing. They told me some crap about not being able to wet-sand on the bumper since it is plastic. I thought the material didn't matter as long as there was a base coat of paint and clear coat on it. I have a few questions. Any help is greatly appreciated.

1. Is wet-sanding bad for the car? How effective is wet-sanding at getting out light scratches?
2. If the bumper has to be re-painted, is this bad? I have heard from people never to remove the factory paint.

Thanks again.

 

1.The detailers that most dealers have aren't very good. They are used basically for washing and polishing cars after service, and preping new cars for delivery. Ask your dealer to use the guy that comes to their dealership to do touch-up work. There are various guys who specialize in this kind of work and in my area the franchise is Colors on Parade. Based on your description I don't think they'll nedd to wet sand it. Polish and buff should do the trick. Wet sanding can get a little tricky and you would only do that as a last resort.
2. Under no circumstances should they have to repaint the bumper, and you don't want them to. Initially the bumper will look fabulous but I'd be concerned about the long term paint durability.

 

Never say never. We bought my wife a '98 Altima SE that had two deep gouges at delivery from being parked end-to-nose in a row of cars. The dealer initially hired a mobile touch-up guy to repair the damage. He did a horrific job. I demanded they farm the work out to their body shop, which they did. Removed the bumper cover, filled in the rough spots and repainted the whole thing. They did a beautiful job and the paint, a one-year-wonder metallic copper color called Nutmeg, matched the rest of the car when we sold it four years later.

So my advice is this: If the body shop is good, let 'em repaint the bumper cover and don't be concerned about it. If you have doubts about the quality of their work, ask your dealer to pay for the work at a body shop of your choice.

 

In this situation maybe not--but if you ever need to have the bumper/hood done-if you go to a great body shop--nothing to worry about. It has been 1800 miles and 3-4 months and all is perfect and more durable than factory paint.https://g35driver.com/forums/showthr...024#post557024
