Its like shopping for cold medicine , soooo many brands all claiming to preform the best, i owned a boat repair business for years and found the only means of obtaining a good shine topside or hull is hard work! the oxidation needs to be removed first, then a light polish to remove swirl marks then a high grade wax...2 coats. The best products ( and i've used them all ) that withstand the South Carolina sun are made by 3M , Super Duty compound with a variable speed polisher/sander ( Milwaukee w/ 3M foam pad) then wash well, then Finesse polish again w/ slow speed wheel. NOTE: Compound & polish applied by hand,only use wheel to remove product. For hulls i use Collinite Aircraft Wax , topside, depending on surface,Maguires Caranuba 2 coats hand applied and machine removed. Do Not do topside in brite sun, heat makes wax almost impossible to remove. Ive done everything from 30 yr old boats to new prep for Boat Shows and haven't had disappointing results yet. Forget all these "1 step elixirs " Garbage! want the best job? work for it ! Steve.
