well depends..... if ur in a "clean" city, then waxing it once every 7 months would be good :) tassie is clean (compared to melbourne and sydney) so ur ok with a good FULL detail evey 6 months. wash, paint cleaner, claybar, scratch/swirl X, polish and wax :) (around 7+ hrs) <_< i just did johnniboi's bonnet and he cant believe the shine on it :D i just went over with full detail and i didnt think the clay bar caught as much contaminants as i thought... might give it a skip next waxing period :)
