detailing involves many techiques, clay bar, cut polish, fine polish, hand wax, wet sanding etc etc...
3 years depends on how much u drive, how often u drive it should still be fairly new; normally i go back to my detailer every 1.5 to 2 years for a detailing and he will reapply paint seal
wax as u dry only helps u to maintain, so u have to use it almost like weekly
a interior shampoo is always good as well cuz mold builds up thru melted snow and wet shoes over the winter time; that's probably one of the other reason why i want detailing lol  |
