On the megs uk forum - it's been sussed out that a second application of NXT 24hours after the first gives the best results.
Also applying megs #16 wax over it apparently works well too - but why put another wax over it when it's so easy to use in the first place!
I've also got the spray wax which i thought was pants until i sussed out it's best used when the car is wet after rinsing - spray a little over over the car then wipe over the car with a MF drying towel or terry cloth, then buff up with another clean MF towel - works like a great quick detailer that way.
