PC vs. TT - opinions needed please

As the title suggests, I'm STILL trying to get rid off those damn swirl marks, and micro-marring on the TT.



In the past I've used 4" SFX spot pads with Menz IP, and have recently moved to Menz Compound Pads with IP.



It seems to be "thinning" out the cobwebbing effect, but there is still plenty of micro-marring which I just can't shift no matter how hard I try. :mad:



My process at the moment (obviously after cleaning the panel) is :



Place a criss-cross pattern off Menz IP on the compound pad

Lube the pad with a quick spray off QD

Dab on the polish to the required area (approx 2' x 2')

Put the PC on the panel and start applying the polish at Speed 3.



Make several passes until the residue begins to turn very see-through.



Then lube the pad, and go over the same area (withough removing the residue) for several more passes until it again turns clear.



Switch to speed 6, apply pressure on the PC, and go over the area once more - for several passes.



Wipe dry with MF towel.



Now, as far as I'm aware - this is a fairly good process (I could be wrong) for trying to cut back VAG paint. But it just isn't cutting back the micro-marring !! I can't even FEEL the scratches with my nail, so it must be right on top.



I have been real patient with using this process, in general it takes approx 1.5 - 2 hours just to focus on the trunk lid !!



All suggestions are welcome as I'm running out off hair ! :wall
 
I didnt have any luck on my sis' old VW with a PC. Once I started using a rotary I started getting somewhere.



I think what you need to do is make a couple passes to remove the webbing you're talking about and then go to a less agressive pad and polish combo after that. If the combo you started with leaves micromarring, then obviously, you're not helping your situation by using the same combo again. Start out with the aggressive pads/polish, then move down the line in aggressiveness. I havent had experience with Menzerna, but maybe try some IP on a polishing or light cut pad after your compounding pad step and then some FP on a polish pad and see what you're left with.
 
What he said, but also, I think you're inducing the micro-marring by your process.



The primary aggression variable with a pc is pressure, combined with speed. You're not using any real aggression until after your polish is gone essentially. Try skipping the fancy stuff (the rewetting and all that) and reverse the rest of your technique.



Start with speed 5 or 6 (with the 4" pad I'd try 5 first) and good solid pressure. Learn to anticipate when the product will be broken down and start to dry. Before that point, ease up on your pressure so that you finish with a full sweep at light pressure.



The way you're doing it now, with all those sweeps (to me, a sweep is one full converge of the working area in whatever direction you're going - so one pass might be 3 sweeps for example) at speed 3 I think you're just wasting product? Not breaking it down, just drying it up. So then when you go to 6 at the end, you're setting yourself up for more marring.



Then of course, follow up with the above advice from Way2SSlow.

Hmmm....that makes sense. Thanks Bob - I'll give it a go the weekend, and see what results I get. :xyxthumbs
 
You might want to try the menzerna polishes for the ceramiclear paints. The super intensive polish and 106FF have worked INCREDIBLY well on my A3 with a PC, and I figure the clear on our cars is probably the same. They did the job pretty quickly too. Maybe just get the super intensive polish depending on what color your car is as it finishes down very nicely.
