Slight Hologramming After Compounding with PC 7424

I've recently been working on my second paint correction job with my PC 7424 xp. The first one came out excellent using just an orange pad and Meguiars Ultimate compound. And I've worked my way around the vehicle and have done a full work down on the hood, but I can't seem to remove some slight hologramming that was left over from an attack by a dirty California blade.

I took a video with my phone to hopefully illustrate what's going on.

My question is what pad/polish should I used to get rid of the hologramming?

I have at my disposal:

M105 and M205
LC Flat Pads 5.5" Yellow, Orange, White, Grey, and Blue
Megs Ultimate Compound

I'm thinking some combination of M205 and a cutting pad might do it. I tried a small section with M205 and a Grey pad with no effect that I could see.

I didn't get to try with anything more abrasive because all of the pads I had were dirty at the time, I'm waiting on some drying right now.

Any suggestions would be appreciated :)
 
:iagree: 205 and White. Generally 105 should be followed up with 205, at least on darker cars.
 
Yeah, I guess it is difficult to see in the video. It's visible when the sun glares off of the finish. I'll give the white pad a shot and if I still can't get it out I'll try another video. I don't think the marring is very deep so hopefully the white pad does it.
 
Doesn't sound like you have hologramming from a pc, but marring from the water blade. Try 205 with a white pad and back to 105 if necessary.
 
Look harder, he said "slight hologramming", you can just barely catch the light roll along the holograms at 2, 3 & 5 seconds into the video.
 
The PC generally does not cause holograms in the paint. On darker vehicles and vehicles with softer clear coats M105 should be fallowed by M205 with a white pad and sometimes M205 and a black pad after the white.

Do a test spot next time before working on the whole vehicle it will save you time in the long run so you wont have to do the whole vehicle twice
 
I tried a pass with the White pad and M205 and it didn't do anything. So then I hit it with an Orange pad and M105 followed by the white with M205 and the result showed almost no change.

Here's another video I took after trying a section out. The section on the left side of the tape is the one that was polished.

Actually the only place on the vehicle that has this issue is the hood. The rest of the vehicle is looking very nice. I just can't get rid of the fine scratches on the hood there. Hopefully the new video I put up shows it a bit better.

It's a VW Touareg if that helps. It seems to have a pretty hard clear coat because I had to use an orange pad with the Megs Ultimate Compound to get some of the swirls out of the door panels.
 
are you cleaning surface with MS or IPA between 105/205?
how many section passes with orange/105?
maybe need to go yellow/105 first?

I've been doing what was described on the bottle. I usually do 3 section passes with moderate pressure, I'd say 10 - 15lbs or so, and then 2 passes with light pressure so the pad spins a bit faster, say just a bit more than the weight of the PC.

As far as between applications of 105 and 205 I've just been wiping with a microfiber to remove all the residue and then occasionally I'll use some Megs ultimate detailer if the 105 is tough to get off.

Not sure what MS and IPA mean, I'm a bit of a newbie.
 
So the scratches from the water blade are not coming out with a 5.5'' flat orange pad and UC or M105. Is that correct?

If so try using a more aggressive pad like a flat yellow, purple wool, or Surbuf pad. If you cannot remove the fine scratch with these pads and M105 it will have to be removed by rotary (or there to deep to safely remove)

The Surbuf pad works great. I used it the other day to remove high temp paint (overspray) off a 1000whp supra. Just make sure you fallow it with an orange pad and M105

That is correct. I do have both a yellow 5.6" flat pad and a wool pad I can try. I'll give them a shot on the section. Just seems strange to me that all of the swirls came out no problem but the water blade marring, which were finer scratches to start with, and appeared to be shallower, are causing so many problems now.
 
The process I've used on my dark car was Meg's UC on white, followed by 205 on white, and finished with 85rd on a gray pad. It worked great for me, no holograms or other flaws left behind.
 
ms-mineral spirits
ipa-iospropal alcohol

Ok, should I be cleaning the surface with that after the pass with the 105? I've got some denatured alcohol that I could use to clean it up.

You're thinking it might be some residual 105 on there marking it up during the pass with the 205?

Read through this article, it could be the scratches you are talking about are too deep to safely remove or it could be you'll need to work them out first by hand and then follow up by machine polishing.

You can exert a lot more pressure to a small area by hand than you can with any PC style polisher, simply apply the M105 by hand.

Thanks for the tip, I didn't even think of trying to remove them by hand first.

I don't think they're RIDS they're just about gone and they don't catch on a fingernail at all. I'll give the hand working a shot and then follow up with a pass of the orange pad and see how it goes. If they can't be taken out without a rotary I'll just have to live with it for now.
