Hey!
Thanks Poorboy! I know some!
Meguiar's #9 is not supposed to be buffed dry as the removal of the dried residue will re-introduce "micro-marring" back into the finish. When using #9, or #82 Swirl Free Polish, always keep a wet edge while buffing. If you feel that an area was not worked enough, add more #9 and continue buffing. Make sure that you wipe off the product BEFORE it dries!
The problem that I think you are having is that you may be using too much product, the surface temperature could be too high, the pad may be over-saturated (should be cleaned after a few panels), and the humidity might be high. Try and do the car when it is cooler like early morining, clean the pad often, and use a spray of QD on the residue on the more stubborn areas. Generally, if the product is hard too remove, you have probably worked it too long. Sometimes, you can do everything right and it will still be hard to remove. Just spray the residue with a little #34 Final Inspection and then remove.
When you are ready to glaze and if you live in a humid area:
Meguiar's has a product called "#5 New Car Glaze". This product has been around for quite a while. The product is NOT "New". This product is in the family of #3, #7 and #81 Hand Polish. But unlike the others, it has been designed for high humid areas. I still prefer the depth and gloss of the #81 Hand Polish over #5 but the #5 is a lot easier to remove if you live in a humid area.
Good Luck!
