Not something I'm that familiar with or hugely fussed about apart from a trio of autoglym products i was given (shampoo, Super Resin Polish and some wax/sealant). The Micra/Shicra is starting to show its age (i.e. go a bit pink in all over) but its nothing a good cutting compound and probably session with a DA wouldn't solve.. anyone do this sort of thing or know anyone that does? and once done, does it need constant TLC to keep it looking perfect(ish)?
