marring/hologramming

i recently took the makita to my 03 cobra, which is black. i used SIP on a PFW pad, then nano finishing polish on a white pad, and ended with po85 on a blue pad. for the first week, it looked amazing, i used KAIO, nothing else, as it is a garage queen. after a week i took it outside to warm it up, and i noticed buffer trails on the door, and part of the hood. it is not all over the car, but certainly in those areas. there were no buffer trails when i put on the klasse, and i used a halogen lamp to check. could it just be the direct sun being a better light source that the lamps?
 
jrock817- Yeah, sunlight is the *best* for showing holograms. The 3M SunGun is a very distant second-best, and IMO anything that shows up under any other lighting must be really, *really* awful.



Heh heh, even *I* can usually finish out well enough with a rotary that I need sunlight to see the holograms :chuckle:



Hey, if you only got them in a few spots I'd say you're doing well.
 
I use a 9 LED light and it shows EVERYTHING but it's very direct light so you don't get to see a large area but it has not failed me yet.
 
Remember the Sun is your boss, if it looks good in Sunlight your golden...no pun intended. You can just hand wax the imperfections out using up and down strokes on the sides. You can use Zaino 6 Quick detailer to take them out...always use a THICK microfibre as long as it is soft. You can hand wax with Zaino 2 then Zaino 5 if you dont want to machine it to perfection which is the way I would do it. Be Well! Ben
 
thanks guys for the feedback... should i just wax over it, and have it look as it did when i first finished it? i hear people talking about another step, using a DA to take out hologramming. also, this is the first time this has happened, maybe because the cobra is black?

I certainly would *NOT* do that. I'd take out the holograms, I would never just hide them. To me, holograms are a very specific type of flaw, one that screams "improper polishing", and I just won't accept that.

That's how I do it.

Holograms are easier to see on black, but IMO it's just something that can happen any time you finish out via rotary. Even experts like Mike Phillips (who has decades of rotary experience) often finish out via DA.

Im confused by this,I was under the impression that because a rotary had a stronger polishing action it would break down the polish abrasives better and ultimately leave a better finish than a PC :think:

Yeah, it *can* leave a better finish *in some cases*. But its uni-directional polishing can cause holograms, and a random orbital's multi-directional polishing won't.



And it's not just about breaking down the abrasives; some polishes like M205 don't break down at all, other products have "easy fracture" abrasives that break down just fine via non-rotary methods.

This is true in many cases, but there is more too it than that.



I get a better finish out of most polishes by rotary over a DA, but that is usually when polishing fir defect removal. Some polishes have really good abrasives that will do OK by PC. 85rd is supposed to work great by PC as a finishing polish.



I think the main thing to do would figure out why the trails are there. Are they deep like PFW would leave or very light and hard to see, like from the polishing steps would have left.



Try to remove them by re-polishing with 85rd, ipa the area after and recheck in the sun.
 
I totally agree that those holograms should be removed pernamently, not by hiding them with z5.



On my new car the dealer left holograms on my car when "attempting" to fix a scratch in my car. Zaino AIO did a good job of hiding it by itself. That was 3 wks ago. I can't wait to go back in and fix them myself.



Keep in mind that certain body curves on a vehicle make it difficult to polish with a rotary...hence a pc will make it easier to polish without negative effects such as holograms.



Also, make sure you are using clean towels gently. You may be overly aggressive with the towels, leaving a hologram-effect on the paint surface.



Finally, like mentioned before, perform an alcohol wipedown on the surface and inspect in the sun to ensure no remaining oils are hiding the true finish. I would start your corrective process by doing an alcohol wipedown (it will remove the kaio), then polish, then another alcohol wipedown. Doing it before polishing means you are preventing the wax from making your polishing pad "hydroplane" on the surface.
 
Meguiars #205 should finish out hologram free with a finishing pad, you might want to consider trying it to remove the light holograms.



The sun or LED lights are the best for finding holograms. I've had a few unexpected surprises myself using halogens.
 
Yea, the sun is king when it comes to finding defects. Try using the po85 on a blue pad combo to remove them. Use slower speeds w/ less pressure when finishing out. GL
 
so i went over the car again, with a blue pad and 85rd with the rotary. i first did a ipa wipe down, like advised to remove kaio... my problem was, i think, overpolishing with the finishing polish on my second step, and i just couldnt see the holograms in the garage. this time i worked outside, and with one pass per problem area, the hologramming is gone. thanks again for tips, and im glad i didnt just cover it up... i have a new respect for black paint!
 
jrock817- Glad you got it sorted out. Yeah, you do have to have the right light to see if you're OK when it comes to holograms.
