I worked for a professional valeting firm for ages and never used so many products.... do all the extra layers actually work? I simply used a good quality shampoo with wax, then built up layers of wax from polishing it after each wash. The paint work is 97, but looks like new. In the rain the water beads of amazingly... cool i know!
so, are all these specialised products worth it then? I would recommend installing the diamondbrite or superguard systems, and maintain regular cleans fortnightly or weekly.
