Okay guys time to set my pride aside and ask for help. I guess I'm a "Hack" lol. I've detailed for dealerships for a few years and always considered myself one of the better as I at least tried to take pride and do a good job in my work. But I just purchased a higher mileage C5 Z06 to daily drive and after some much needed buffing I've realized I can't finish a black car with a rotary without leaving holograms, marring, etc.



So now my question is, I just ordered a PC 7424 and CCS Orange and White Pads last night with some Meguiars 105/205. What do you all suggest to help me correct my rotary hack on this hard corvette clear coat?



Thanks,

any help greatly appreciated.
 
Just a question others may ask, what size pads did you order?

I've had good results with orange/105 then white/205 but I upgraded from a PC to a Flex as well.

Good luck, I'm sure others will post up....

I couldnt pull it out in the sun cause its raining but tried to capture the worst with my flash on my camera.



I used 3M 8" pads, 105 with white compounding pad and 205 with grey polishing pad.



I ordered 5.5" pads with the PC.
 
Blake Veatch- Welcome to Autopia!



You might find the PC quite hard-pressed to correct that, IME it's merely borderline OK as a polisher on harder clears like yours.



I myself always needed little 3-4" pads to do such work via PC. Gee, *now* I tell ya, huh?



If you're gonna use M105/M205 (and whether I'd do it that way is a whole 'nother matter), I'd try do do as much as possible with the M105, using mild pads for the more gentle work. I'd be *constantly* cleaning the pads and stripping the oils off the paint (with IPA, or PrepWash, or even PrepSol) as they can conceal some pretty awful holograms.



By the looks of that last pic, you need to do a fair amount of work with the M105, and here's the kicker- you gotta do it right. M105 can leave some pretty serious marring of its own and it looks like that is part of the problem here; those aren't just holograms, they look like a bit more than that to me, though it's hard for me to diagnose over the internet.



Be sure you have *GOOD* lighting for inspecting this work so you can tell whether or not you're making progress. Pick a good representative test spot and get that small area just right; fine-tune your process before you do the whole car.
 
Thanks Accumulator, thats what I needed to hear:hairpull I was hoping a PC would take care of it :faint2:The car had been buffed when I bought it, I could see the swirl marks under the fluorescent lights in the garage. At least now I dont see them under those lights but they are obviously still there from the flash on my camera.



If not the 105/205 what do you suggest?
 
From the looks of your second pic it seems that you need more correction. Try 105 and wool since the cc is hard. Use good technique so that it finishes out well. You should be able to use the pc to polish and refine after. You'll have to play around with different combos though.

Yikes, if you could see 'em under fluorescents then they were really awful :eek:

At least you have some reasonable way to see them. I had to buy the oh-so-pricey 3M SunGun!

I can't help but wonder how you'd do with 3D UNO. I haven't tried it (and I hardly ever recommend something I don't have experience with!), but people I listen to say the latest version is simply wonderful.



Ya know, my *honest* opinion here is that the polisher is gonna be more limiting than the products. If I were doing that car, I'd use my Flex 3401 or my Griot's Garage 6" (definitely not my PCs!) and I might do OK with the M105/M205.



I wouldn't try redoing it with the rotary as IMO this isn't a good candidate for practice at improving your technique. I'd rather see you sort it out with the minimum of (additional) clearcoat removal. Along those lines, if you find some Random Isolated Deep Scratches ("RIDS") I'd probably leave 'em be. I'd be concentrating on getting rid of the swirling/hologramming/etc..

I tend to agree, it looks like it needs more correction. If you can photograph them, they most likely aren't holograms. On a car with lots of paint, like the vette, you need to pick a small area and figure out your approach, then do the rest of the car.
