I have been going over my car panel by panel using the following process:
Ultimate Compound with Polishing Pad -> Ultimate Polish with Finishing Pad -> Gold Class Carnauba Plus Liquid with Finishing Pad
Initially I was quite impressed, particularly with UCs cutting ability and resultant shine, but I'm now getting very frustrated.
I'm working late evening, so I don't have any sun to check my work, and am instead relying on a Brinkmann Dual Xenon. Once I've finished a section and pack up for the evening I'm quite impressed, but by the time morning comes the car is covered in a slightly blotchy appearance that is almost impossible to get rid of.
At first I thought this might be due to the Gold Class sweating overnight, but I think this would wipe off quite easily, especially with a mist of GCQD. The thing is, it doesn't... If anything the QD makes things worse! Where the QD has been directly sprayed seems to leave the paintwork darker, and wiping it around the paint does not seem to give even coverage. Even spraying on excessive amounts of QD doesn't seem to work as the different areas dry at different rates.
I should point out that all of this observation is happening in the morning under mostly fluorescent lighting. Once I move the car out into the sun, the blotchiness is almost impossible to see, but instead appears as a kind of patchy greasiness.
Thinkinkg about this in more detail now, I first noticed this effect when I applied Zaino sealant after the UP stage. I guessed at that point that it was because Zaino wanted a fresh clean panel to start with, and perhaps there was some incompatibility with UP. Now I am beginning to think that UP is to blame again, and the polishing oils left behind are preventing GCCP from bonding to the paint.
Could this be possible? Should I really need to IPA wipe down each panel before applying GCCP wax?
I like the (initial) look of GCCP, but this issue is making me seriously consider going back to a Zaino routine, which would be a shame because I fancied a change.
