what`s wrong with this paint?

This is my brother`s new car. I detailed it this weekend and this is how it came out. the splotchiness was definitely there when he bought it. It`s not that noticeable, but it bugs me. Is this a bad respray, or is it something I can fix?


These pics are after one pass with Menzerna SP400 on a white lake country pad. One pass with Menzerna IP on orange pad. Then another pass with the SP400/white pad.



 
From the picture I would say re spray. If you know someone with a paint gauge you could tell for sure. If it is only the hood, I really think re spray. Take it back if still under warranty
 
It`s just the hood. He just bought the car and there`s no telling when it was done or where.

I`m not too familiar with paint gauges. Would that just tell me if the paint thickness varied a lot?

It really seems like just the hood. but the other body panels on the car are so small and contoured it`s tough to find an angle that would show it.

I know the dealer he bought from slathered all sorts of stuff on the tires and trim. overall I`m happy with how it looks. it`s not that noticeable unless you`re right on top of it.

With a paint gauge factory applied paint will be for example around a 115-140 reading and a respray would read at something like 200-280. You would see a huge difference.

I would lean towards a poor respray. Silver is difficult to lay since it is almost a pure metallic mix. It is very easy to stripe if done carelessly or in a hurry.

Another way to tell is to look at where the hood meets other panels like fenders or door. If it was done improperly there will be a tone difference as they probably did not blend the paint.

From your last pic it looks like the hood was resprayed.

I see what you`re saying about the last pic. In person there`s not an obvious tone difference. the bumper has some clear bra next to the headlights, which is a big reason there`s an obvious difference in that pic. A lot of it is the different light angles.
 
So just to make sure I understand, the problem is uneven base coat correct? That can`t be fixed with a buffer.

That is true if it is a respray. A paint gauge would confirm. Ad you can see pictures are hard to confirm.

Where are you located? Maybe someone who is close by could help.

Fort Worth Tx. Specifically the mid cities area.

To clarify, you said easy to "stripe." I`m not talking about the wide strips of light and dark running lengthways. That`s from the contour of the hood. it has a hump in the middle. I`m talking about the blotchiness, or dappled look it has. Almost like the pattern you`d get under a tree from the light coming through the leave.
 
What was your process to try to clarify the paint ???

Machine and Model ?

What size backing plate and pad ?

Which Lake Country White Pad ? Is it Flat ?

How much downward pressure. and at what machine speed ?

If you only did 1 pass and its a Random Orbital machine, you were not even getting close to doing anything to this hard paint - even if its a repaint..

I bought one of these new - a 2002 Z3-M Coupe in Titanium Silver, so I know a little about that paintwork...

Let us know..

PC 7424 DA. spread with speed one, then went to speed 5. I let the polisher work under its own weight. 5.5" backing plate and pad. CCS I believe. the one with the dimples in it.

I wasn`t trying that hard to get it out. didn`t want to get to agressive, I haven`t done this in a while.

When did see it wasn`t coming out I went to the MIP with the orange pad. Same speeds. an older 6.5" pad. cant remember who made it. It has a convex shape underneath with a beveled edge and a hole in the middle.
 
Well, it`s entirely possible someone did a quik re-spray to freshen it up or take care of accident damage, etc....
 
That definitely looks like a poor respray job.

I had a metallic silver Subaru with similar looking paint on one of the doors.

Metallic silver is really tough to match... and realistically won`t if you`re just spraying one panel.
 
I would have to go along with the bad repaint crowd, but since you`ve got Menz 400 try that on your orange pad, put about 5 pounds of downward pressure and do about 4-5 passes and see if there is any difference. If not, you know there is not much you can do for it except have it resprayed. But if you are happy with it just drop the top and have fun!

Oops. That`s a typo. Sf4500 not 400. Menzerna IP(800?) is the heaviest thing I have right now.

Well, since you have a Finishing or Jeweling Polish, (SF4500) instead of a Compound, it is no wonder you did not get the result you were looking for..

Menzerna Intensive Polish (PO91E) is still a Polish and will not really be able to correct paint that is in need of a lot of correction..
It will help to get some good pads that are designed to be used with a compound, if you want to pursue this further..

A 5" backing plate and pads would allow the machine to rotate the pad more, but you need to up the speed to 6 and press down and go slowly, watching what is going on while you are doing this, in good lighting... It would also be way easier to handle under speed and get into more places where the big dog 6" pad cant go easily.. Just a thought...

When you washed the car and used a Claybar or rubberized towel or pad, what came off of the paint ?

If you had clay, What color was the gunk in the claybar after working one part of the hood ?

Did the paint feel really smooth after this step ??

Whenever I correct any German car - even Jet Black with any of the Menzerna Line products, I always work the product until it is about gone, so I can get the most out of their perfectly milled correction abrasives...

A good way to tell if this hood has been repainted is to open that huge clamshell hood and look at the top edges of the front fenders and the edge where the hood meets in front of the doors...

It is all painted in those places, and if its different, or you see overspray anywhere in there, then it indeed was painted..

Look on the underside edge of the hood, all the way around to see if its perfectly smooth and painted or something different..

If you get really close to the hood, can you smell paint fumes coming out of it ??
Good Luck !
