I'd rather invest some time twice a year waxing (before summer & winter) rather than lots of frequent upkeep.
What works for me:
- with dishwashing liquid (Dawn works best - this will strip off your old wax so only do it if you are going to apply a new coat right away)
- Meguiars clay bar & lubricant
Paint correction (if req)
- Menzerna Super Intensive Polish
- Menzerna micro polish
- Wolfgang paint sealant 3.0
