The Handbook just says to wax the car,and if you use a polish make sure you wax it after no mention of the 12 week mark,Auto glym deepshine is both,but more of a wax than polish(ALSO SAYS IT PREVENTS SWIRLS),auto glym red is what you use if the paintwork has gone dull,that has more cut but also contains wax.I`ve Used auto glym on my touran and the 13 year old astra that i scrapped,the astra`s paintwork was often commented on by passers by who whould say how amazing it looked for a 13 year old car,it truly looked like it had been resprayed. To be honest i`d not really thought about wax and polish being different,but i see your point now.When i get chance i`m going to seal the paintwork with auto glym gold which is purely a sealant/wax.
