A buddy of a buddy of mine bought this vehicle and it indeed has all the problems aforementioned. The paint was in terrible condition, the rear left fender was replaced at one point and some bondo on the right rear fender. There was over spray of paint/clear coat all over the car, tree wax and scratches everywhere. The audio has now been basically fixed, the clutch still chatters and barely grabs, and the interior is in very poor condition still. But all these things will be taken care of eventually (I think).
My buddy is in the midst of doing some cosmetic repairs, so he hired me as I'm an avid detailer to see what I could do about the horrible paint. So I decided to give this NSX a detail because I love NSX's and I hate to see the car in the state it was in, and wanted to make some cash.
Here is what it looks like now after I spent 5 + hours on it. I'm sure the member above can contest to how poorly it looked before. This is what I did to it. I didn't take any pics of before detail though, I should have...
2 bucket car wash
the most clay bar-ing i've ever done (Megiures claybar)
1 stage abrasive compound (Menzerna)
1 stage fine compound (Menzerna)
1 glaze wax (RMG)
1 sealant carnuba wax (Liquid Souveran)
It's funny because apparently the previous owner said he was selling it so cheap because the paint was terrible and that it would have needed a full paint job. Amazing what a good detail can do eh! I now want an NSX even more than before, even with the very limited seat time I had with it.
