Im the same as Ken ,I only use the 'Sol' I've heard a number of people having issues with the 'set ' part .

Dont fear using the Klear in the AB ,it really wont do any harm ,being a polish its self levelling too ,so dont be scared to put it on ,which I would recomend ..even if its just on the areas where the decals are going ...it will make life easier
