Preventing Rust

I had a 2014 Sportsman 570 that I just sold and bought a brand new 2016 Sportsman 750 EPS. My 2014 had a massive amount of rust on it. I bought it used and the rust was there when I bought it. IT did not make sense that a 2 year old quad had so much rust. I figured the previous owner left it out in the rain all year round for it to look like that, but the dealer I bought it from used told me that’s normal.

When I went to sell it privately, every potential buyer was turned off by the rust and said its unreal for a 2 year old quad to have that rust, as I thought too.

Anyways, I want to prevent my new 2016 model from rusting like the 2014 had. I have had many used quads and dirt bikes, these are the two newest I have ever owned, most were late 90s and early 2000s and they did not have as much rust as the 2014 Sportsman. Maybe Polaris uses cheap paint or something, I don’t know.

What can I do to prevent rust on the new quad? I bought some Polaris Never Rust spray I found in the store, I had never seen before. I have asked around and no one knows anything about it, no one at the dealer has an information or ever used it either. Is this safe to use / spray all over the quad? Is it worth it / does it actually help? How often should it be used? Can it be sprayed on the motor / exhaust? How about on joints, will it affect the grease and cause issues?

Any help is appreciated. Thanks in advance.
