Certain LSP's (Last Stage Products) can look better on some colours; whites and silvers can look better with a
sealant, whereas, darker colours tend to look better with a
wax BUT you can also mix the two, there is no right or wrong
If your Kuga is light coloured and as you already have the HD Wax, I would go with
Autoglym's High Defenition Cleanser Kit before applying the wax and if the paintwork is dark, I would also use
Autoglym's Ultra Deep Shine, after the cleanser and again before the wax.
I used this combination on a neighbour's car
