Challenge: Paint fence (take two)

Take Two.  We have set this challenge today as a) the sun is shining and it means a good dry evening(typical - it's Monday) and b) leave it any longer and we know we won't do it.  So at some point today I need to fight my way back through the traffic to B&Q; on top of stopping for kitchen essentials, getting the dry cleaning in and getting my dress to the menders readuy for a wedding in two weeks (I swear most domestic goddesses can sew - do I need to take a course in this too?)  Not to mention a long day in the office ........Any tips on painting fences most welcome.....
