Zaino leaving blotchy patches

Zaino Z-5 Pro and Z-2 Pro both seem to be leaving these blotchy spots, the only way to get them out is to spray with Z-8 and then buff until its dry. Z-6 doesn't seem to remove them as well. It seems like I can buff like mad and get the spots to diminish, but they never go away unless I hit them with Z-8.



It has done this with a couple of cars now. I always start with Z-AIO, which I love, but 2 and 5 (and Z-CS for that matter) require Z-8 before they look nice.



At first I thought I was applying too much so I did a very thin 2nd coat (Z-FX enabled, waited 45 minutes) using a PC with blue LC pad and that didn't help.



After Z-8 the paint looks fantastic, but I am spending too much time in between coats.

Use a white pad to spread it. That will work.
 
I think the problem is the Z-AIO. I never had any problem with Z-2Pro or Z-5 being blotchy, but the one time I used Z-AIO the whole car was hazy...I apparently used too much.

I do remember reading that you had to use Z-AIO before Z-5 or Z-2 unless you enabled them with Z-FX, which I did with the Z-5. Hmmm.... maybe you're on to something, maybe I should just machine polish (this time I used PO106ff and Z-PC Fusion) and then go straight to Z-5 with Z-FX. Although the 2nd and 3rd layers were still blotchy, you would think that the Z-AIO would have been completely covered by then.



Or should I just switch to Menzerna FMJ? I hear good things about it.

I do believe you could be spot on. A fellow Vette buddy loaned me his bottle of ZAIO to try. I could not get it to wipe off to a high shine finish. I had to wash the car again to remove the hazing. It jus might be me because I'm an amatature and an ole-timer, but I did not find it easy.
 
The ticket to the zaino line is to apply whisper thin. If you can see it on the panel, you applied to thick. To get a thin layer, I run a line on my applicator about the thickness of a spaghetti noodle. That typically does 1-3 panels. By applying thin, you shouldn't have any problems.

:goodjob



Like Greg said "Thin to win" with zaino. :grinno:



Also if you are using ZAIO by machine, work it in till it about disappears into the paint. You will find that there is very little left to remove.

Thats exactly what I did. I used a gray pad with a DA, applied a very small amount, and then "worked it" (with no pressure, pretty much just machine weight) until it basically disappeared. In some spots you couldn't see any at all.



With the Z-5 when I tried it with the DA, it didn't want to disappear like the Z-AIO did, no matter how long I worked it. I used speed 4, maybe that was too slow?



I have Z-CS sitting on the truck right now that I will remove tonight. I was going to Z-8 after that, but I might just wipe it off with a damp towel and try again with whisper thin Z-2 to experiment.
 
I'm old fashioned .. I still use Z-1 .. last polish out I used PoliSeal then the Z-1 then Z2Pro etc and all seems well.



I still get this funny feeling the Z-1/ZFX or whatever is required to set/bond it is a scam.



Its been a month now and when I did it I never used Z-1 on the roof over the PoliSeal and there is no appearance / beading difference and the car is washed 3+ times a week.

I honestly think the problem is with the Z5 by machine. I highly recommend applying z5 and z2 by hand as it allows you to get it VERY thin. just to have enough on the pad to spread into the panel probably is to thick.



Here is my tried and true method of ZCS:



-Z6 wipdown prior to application to ensure a clean surface



-1 initial mist on the applicator (this is the only time I mist the app.)



-1 mist per panel ONLY, however, I use 2 on roofs, hoods, and trunks.



-after 1 mist on the panel, about 10-12" from the surface, I proceed to use the provided Zaino applicator to fully wipe on the product once. Next, I go over what I wiped on 2 more times. Basically, you're wiping it on 3 times per panel, but it doesn't take long.



-Repeat over the entire car



-Enjoy

I've used Z2 and Z5 by machine with no problems, and in my experience, *I* get a thinner layer by machine. (YMMV, I seem to suck at hand-applying anything thinly and evenly).



Here's what I think might be the problem:

Instead of working it in, just "apply" it. I usually use a 4" SFX-3 blue pad to apply. I'll apply a small amount of Z to the pad, tap the pad on several places on the panel I'm working, then run the buffer over the area on speed 3 or 4. You don't need to work it into the paint, just look for even coverage. If you have the right amount of Zaino on the pad, you'll just barely see the little smudges left behind. You can squirt a small amount of Z6 or Z8 on the pad every few panels to keep the pad just slightly moist; it seems to make the Z2/Z5 lay down a little more evenly.



Using the 4" pad and PC, I can easily get a layer down on a car the size of my WRX with about 1/4 oz. of Z2 or Z5.
