Can I layer this on top of wax?

The person representing the company doesn’t know what the hell he’s talking about when he says you can put this over wax. You could put anything over wax such as dog crap but, I doubt it would help out. Wax ALWAYS, ALWAYS goes on as a topper be it a polymer, ceramic or a graphene you are topping. Why? Wax has a relatively short life expectancy. A few weeks or less. If you put wax on first you’re wasting your time, money and effort. Don’t take my word for it, use a little effort and do the research, there’s plenty of info out there. Turtle Wax made the same stupid claim as the gold eagle rep. in one of their ‘product info’ pieces on their web site. Sent an email to them explaining the error of their ways and they sent back to me they would have it corrected. Did they correct it? I never went back to their site to check on it.

Can this offer 1-yr protection for a daily driver in a 4-season climate - snow/sand/salt in winter?

I'm near Philadelphia Pennsylvania, about 40 minutes north. I've seen up to 9 months of solid protection so far on my clients vehicles. Looks like 1 year is possible for a daily driver here. But time will tell.

I have invisible bra installed, can i use on it?

Yes. Prep the area on top of the clear bra.

How long will the product last once the bottle is opened?

Hi. It is recommended that the product be used within 2 years after opening. Hope that helps!
