Hi guys,

About to get my 350Z Convertible 2005 wrapped.
But before this happens, I need to get rid of the paint on the plastic part right behind the back window.
The paint is falling of at some parts.
What is the best way to go at this?
Sanding? I'm afraid I will sand some dents in the plastic part.
DOT3 or 4? Is it safe to use on just 1 part of the vehicle?

Your thoughts please

Roger

 

Which part are you referring to? Post a picture of the failing paint if you can.

I took a bit of wrap and covered it up

 

I didn't realize that entire panel under the 3rd brake light was plastic. There are paint stripper chemical products, but most are only safe for "Flexible plastics" such as bumpers. Rigid plastics like ABS will get eaten/melt if using one of these chemical strippers. If that panel is confirmed to be metal. Then you're safe to use a stripper product, best done with the panel removed from the vehicle of course. I would stay away from brake fluid as that stuff is very difficult to keep from getting on good panels that you want to protect.

Wet sanding might be your only option. If you take your time and use a less aggressive sandpaper with a foam block, you won't have to worry about taking off much material. Just level the rough areas where peeling has occurred. You can use some painters tape to help protect exposed plastic or body lines.
Good Luck!

I *believe* that the tonneau cover is fiberglass. I know the roadster trunk lid is fiberglass.

I think sanding is your best bet unless you're trying to remove ALL the paint from the tonneau/storage lid. You can remove the third brake light when the tonneau cover is in the 'up' position. I think there are two exposed nuts.

 

Correct, already had it removed.
I'll check if I can remove the whole panel ans start sanding.
thx for the info guys.

 

Alternatively, I suppose you could try a thin skim coat or glazing putty to fill in the area where the paint has peeled off and then sand it smooth. Like paint, vinyl will show everything underneath so it needs to be the same uniform layer.

Good luck!
