I just whip the seat and tank off, use a pump spray and a brush and Bob's your Uncle. I get my ACF from Transair Flight Equipment in a 4l container - they also do a 20l - which is great value compared to a spray can. I've found that the neat stuff is also a lot thicker consistency and covers/stays on the bike better. It does run though, and you need to wipe it off those areas where you don't want a bit of slippage.
On the subject of valeting, there was a nice blonde chick touting for business at Weston Bike Night a while back and she's mobile, but I didn't get her number as I do my own.
