Which products are recommended to preserve and maintain a coat of 845?

There are 2 options:

1. No. S-845 Speed Wax is the most effective option if boosting shine, gloss and protection are your primary objectives.
2. If a gentle cleaning (to address dust/prints/droppings/water spots) requiring surfactants is your primary objective, No. 520 Detailer is your best option. No.520 will also leave protection.
On average, S-845 Speed Wax will be 30-40% more durable than No. 520 Detailer.

Collinite 845 can also be layered over itself if additional protection and shine are desired
