I'm in colchester mate
what wax are you using, the NXT wax your using should be really really easy to apply, if your using the applicator pad it kind of just smoothly runs over the paintwork rather than having to work it in at all
when using the NXT (which i may change from soon) I squirt a pea size blob onto the applicator pad
sometimes i'll add more to the pad depending on if its needed, you really don't need alot though
I was doing 3 panels, then after i'd coated the last panel i'd buff off the first, seemed to give it enough time on the paint before buffing off without much work
