Yeah this could be the problem. After a 2-pass under the work-light, all seemed well. I should of rechecked more closely with a torch because it felt like it was almost a little too easy/fast.

So I've royally ****ed up now. Not sure how badly.

In a nutshell - theres now a 'dull' finish, on an area around 6x6 on the paint. Almost like a matte finish. Not shiny like the rest.

I was using the menzerna black finishing pad and the menzerna super finish PF3500 on the area in question. Previously I was working down in small sections on the side of the car with the black hexlogic and scholl S20 at low speed. I then tried a new section on a higher speed. Both got good results at removing almost all of the marking which was causing the light to scatter.

I moved on again and swapped to what I'd consider my absolute softest/lightest pad and polish combo. The polish apparently has no cut, and the pad is the softest they make from what I can see. After a few mins working it into the paint I've been left with a dull matte like finish?!

From what little knowledge I have + google: I've either:

A. burnt through the clear coat? Though I'm not sure how, as I'm using the mildest pad/polish combo
B. 'overworked' the polish?

Is there such a thing on 'overworking' polish?? What does it look like? I'm scared at even attempting putting the orange pad to the paint in-case I have in fact ballsed up the clear coat.

I'll try and post some pics. Any help appreciated

Did the pad have any of the paint colour on it when you took it away?
If you had no clearcoat you'd be polishing on paint so the pad would come away the same colour as the car (mildly)

Not that I could see of, the car is dark grey and the pads are black. I tried using some detail spray + a white applicator pad over the area. Then tried it with some white polish on the pad and rubbed it over the area - no colour was on the applicator pad after going over it several times...

Well if you've used a white applicator pad over the area after you think you've 'gone through' the clear coat, I'd say you'd be fine there.

I'd like to say someone with experience with those particular products will come along soon with some technical advice.
I wouldn't worry too much on the clearcoat issue, I'd say your ok there.
Pics might be helpful though....

Mate I would seriously put a picture up just show us what is going on. I don't mean to be rude but it's obvious that you are clearly struggling, so before you carry on with another pad and polish it's best to put some up.

Like Chongo said but some pictures up. Mick Will be the Man to help (He has really helped me) or a quick PM to Stangalang and i am sure Matt will be able to help.

Ill also see whats going on when pictures are up to see if I can use my experience on this.#

Also where are you based? If you local I will happily come over to have a look.

It's very difficult to photograph:







You can see how clear the reflection is, and how 'murky' it gets in the affected area.

And you're right, I'm totally out of my depth here in a sense of I don't know what it is so I'm not attempting to fix in case I end up doing more damage. You live and learn eh!


Edit: and I'm based in South Wales unfortunately Alfie lol

I would have got a 2nd hand panel from a scrappy to practice with first before jumping in, only saying

I've detailed 4 cars before this with amazing results. Never done Nissan paint and haven't really used anything overly agressive. Scholl S20 is a medium cut, the orange hex is a medium cut. In my defense it's not like I've dived in with the heaviest cut pad and compound I could find.

This hazing on the paint has been caused by polish, not a cutting compound...
