i ve done a few in the last couple of months, i just use a pair of step ladders and do the normal lambswool and squegee it off then detail it, but i have the lamdswool only damp, and when i squegee it off i have a towel underneath and an old blanket on the floor.
its just trail and error , and you ll find you re own way
my way is completly different to a friend of mine,
hope i was any help to you.
p.s if you dont already try some upper body endurance training it does nt half make a difference!
