Invest in a hand-held light to show swirls in the paint-worfk beforehand and after the specific treatments, that is if you want to go professional on this route. Pay equal attention to the under-carriage which are poorly represented in some of your treated vehicles. Remember that although the carriage is not visible directly, it still kills the look when the caked-on dust gets illuminated in the midst of halogens on road.
Although no one would give a damn on these issues, these are there subconsciously and make up for that 'foolish-first-impression' judgements.
To see the flaws mentioned above try taking a couple of snaps with a strong halogen flash. Nonetheless, good work on those cars. I can see at least 80% improvement on sheet-metal you went on. Go beyond them for the complete effect.
Also, for flawless finishes stick to professional series. These canned polishes for regular consumers are merely 'over-priced' finicky junkies out into unprofessional hands. To see a wax's worth, study its industrial application history religiously.
Then again, you are working on factory 800-grit orange peel so i can't blame you completely.
Regards.
