Had mine done from New without letting VW prep the vehicle at all as all this would have done is given the Detailer more work and cost me more.
Full clean inside and out, machine polish.
Gtechniq Crystal Serum
Gtechniq Exo v 3
Gtechniq C5 Wheel armour
Gtechniq il all interior (Alcantara seats)
Gtechniq L1
Left the Cali early morning and collected teatime next day.
I now wash it with a good quality mitt and two bucket method at a local garage which has a wash bay and lance.
Nothing sticks to it and it is almost a pleasure to wash.
Guaranteed 7years but Detailer reckoned with the Exo v 3 I will get 10.
I'll probably take it to him once a year for a checkover and valet for about £50. Required to validate the guarantee.
This thread shows it from post 120
Should never require polishing.
