I have bought some micromesh cloths and have spent quite some time working my way up the grades but I don't seem to be able to get the WOW shine on it

Now, I am a buffoon, and this is probably the first thing I've done that requires this much ... patience.
But I wonder if you guys can throw some tips my way - some dos and don'ts for serious beginners like me.
Many thanks in advance
Joe.
P.S. Why does my Humbrol Gloss black go so 'orange peely'

and why do my finger prints keep showing on the helmet after a while sanding even when I'm wearing latex gloves?!?
