I do what mbounds does
that 3M finess-it is da stuff
try a spray bottle with water and a SMALL amount off liquid detergent, lightly spray 3-4 feet of hull then take a chip brush and apply the 3M Finesse-It II polishing compound(I buy it by the gallon) ,high speed buff in,let stand ,buff again with DRY wool bonnet,to keep the bonnet dry and clean turn bonnet on side and hold a small square piece of wood on it while the high speed buffer is on preferably away from the boat because this slings all the excess off the bonnet , takes practice ,kinda dangerous be carefull.I use 2 or 3 bonnets on both hulls just to keep them clean and dry
Then of course clean rags with your elbows behind it!

this works on fairly new hulls
