I just bought a new TL and asked the sales rep when I could wax the car and didn't get a very good answer. This car was manufactured sometime in July so at most it's 2 months old. I'd like to get a good wax protection on before the winter. Any suggestions on when I can/should do this and any particular products that I should consider. With previous cars I've used a product called Liquid Glass which says it's key ingredient is CRYSTAL CLEAR CARBON. I've had good success with this. Anyone with experience or opinions...? FYI my TL is black on black.

 

Your fine, wax whenever you want.

 

Cars are baked at the factory and can be waxed the minute they roll off the line. For a winter product I would suggest a sealant; there are many on the market. Off the top of my heads ones that will get you through the winter and look good:

Zaino Z5 pro
Jeffs Werkstatt Acrylic Jett
Poorboys EX-P
Menzerna Full Molecular Jacket
Klasse HGSG

Tons more but that should get you started.
