Guys how often should I apply Collinite in my car considering it is enrolled in Big Berts Optiguard Program? Can I also apply Collinite every 3 months simultaneous to the Optiguard maintenance? Or is 3 months overkill? Thank you.
collinite 476 would last 3 months only if there's no rain... usually it lasts 3-4 weeks.
the other collinites are less durable than 476, but are still better than the other OTC waxes
