I've got 2 coats of wax on now and am not that impressed tbh.
what aren't you impressed with, the shine the beading or something else?
if its the shine then you could try another polish, i personally don't think that mer is that good. i currently use megs stage 2 polish, if you want a further shine then you can use a glaze (with wax on top)
Also i'm not really a fan off waxes that come in a bottle and prefer pure waxes that you get in a tub i use, collinite 476s followed by collinite Marque D'Elegance (No. 915)
what colour car do you have
