poorboys blackhole,autoglym srp and dodo lime prime are not polishes
blackholes a glaze,srp is full of fillers and has very little to no correction and lime prime is a pre wax cleanser with mild abrasives
if your want an easy to use real polish use 3m or menzerna but will need to use a machine polisher.youll get very little correction by hand
if your just looking to make it look good and hide and swirls/marring then use BH or SRP followed by a good wax
