Looks like the clearcoat is beginning to fail

A friend of mine dropped their car off to me the other night for me to buff out while they are on vacation. He wanted me to see what i can do to make it look better.

It's a 2002 Nissan Sentra SER with over 100,000 miles that is starting to fade out.

The next day I pulled the car outside and washed it and then inspected the paint. It was really bad. All of the painted metal surfaces of the car looked like they have a pitted or sand blasted finish to it as well as having 1/16" to 1/8" diameter opaque white spots throughout the entire finish. And again these are only on the painted metal surfaces. The painted plastic surfaces like the bumper covers, mirrors, spoiler, door handles etc... do not have the pitted sand blasted finish or the white opaque dots. They are just faded, which i kind of thought was odd. Maybe the different additives in the paint that the factory uses to paint the plastic parts somehow affected how the paint aged and now looks.

After washing the car I clayed a small test spot on the roof and the surface still had that rough sand blasted texture look and feel to it. So I took some M105 on a Tangerine 5.5" HT pad and my G100 and made a couple passes and it did offer some improvement, but it was taking a while so I got out the rotary and burgundy SOLO wool pad and did two quick passes with M105 and then followed back up with the 5.5" HT pad on my G100 to remove the slight buffer trails in my test spot and the surface was now smooth as glass and glossy. I was able to remove the sand blasted texture from the paint, however the small opaque white dots were still left behind, which I expected because i believe it is the clear coat beginning to fail. the test spot looks so much better than the rest though.

Here is a picture of my test spot on the left side of the roof, and the rough sand blasted texture on the right. You can see a distinct line where my tape was and how much crisper the reflection is and much more glossy on the left.

Another angle.

Here is more of an overhead look at the same area. In the lower right corner you can see the white opaque dots that I was talking about a little better, that are throughout the entire finish on the metal painted surfaces. It's got to be the clear coat failing.

I'd like to get this car looking as good as I can get it, but i don't know if i want to spend too much time compounding with wool and foam pads and then following up with M205 polish and then wax for the entire car considering the condition of the paint. I know i am not going to be able to remove those opaque white spots, but I would like to get rid of that sand blasted texture and get it looking as good as i can in the least amount of time. Any suggestions for a speedier process while still having a good outcome?

I have: M105, M205, D151 Paint reconditioning Cream, M83, M80, Megs yellow polishing pads, Megs burgundy Cutting pads, Megs Tan finishing pads, 5.5" CCS Orange, Yellow and White pads. 5.5" tangerine and Cyan HT pads.

What are your thoughts?
 
FWIW - the test area looks 100% better. I'd explain to my friend exactly what you explained here about the possible CC failure and let him know that you can;t work miracles. Chances are, he'd be impressed by the test panel though. I'd say polish it on out. If the paint is already failing, you're not going to hurt it anymore than it already is.
 
Thanks.

Yea, I told him when he dropped it off that if it is just oxidation, I should be able to remove it, but if it is indeed clear coat failure I will not be able to remove that.
 
I would guess that the process that you have outlined would be the fastest. You have made a huge difference and I am sure your friend will be thrilled with the results, after all his eye won't see half the stuff that you see as a detailer. It is a small car so it shouldn't take but an afternoon to finish once you get rolling on it. Good job so far.:bigups

Thanks.

Yea, your probably right.

I think it will take me a bit longer than an afternoon though. Especially when you are as slow and take as many breaks as I do. :D Also, this will be my first rotary car. :eek: scary, right? I've played with the rotary on a few panels and with some localized wetsanding, but this will be the first whole car I use it on. I figure it is a good car to practice on to get some more experience with.

Well it looks like a well rounded car with not too many sharp edges, go slow on the plastic painted surfaces and be mindful of the door bumper trim pieces and any rubber window seals as they will burn easy and do the side mirror housings either by DA or by hand. It is incredibly easy to cut through the paint on the end of the mirror housings with a rotary. Go slow and you will be fine. :bigups
 
I would also suggest you tape over the gaps between the doors and fenders and hood or just stay about a half inch from them with the edge of your pad. The spinning pad can bite into those gaps and take the paint off the edges pretty quickly with a wool pad and compound.
 
The results are night and day. You took the paint from a milky finish to a nice reflection...they should be happy with that turn around.

Yep I was definitely planning on taping the body panel gaps as well as any other sharp edges and the door molding bumpers. I don't want to accidentally burn anything if I can help it. :)
 
After working on that car in the evenings and on the weekend last week, I finally finished the car.

This was the first car I have ever done for money. All the rest throughout the years were either my own vehicles or a family members vehicle.

I think it came out rather well. :yay
