My current combo is:
Clay: Bilt Hamber Soft Autoclay
Shampoo: Meguiars Gold Class
Then a choice of either:
Polish: Tripple All in One
Wax: DoDo Juice (multiple versions to match your paint colour)
or
Sealant: Zaino Z2-Pro
Then also...
Wheels: Poorboys Wheel Sealant
Tyres: Meguairs Endurance High Gloss Tyre Shine
As above, Detailing World will give you a wealth of advice and product recommendations. Get your wallet ready but the shine is worth it
