Anyone ever try using Nu-Finish Car polish or the Nu-Finish Scratch Dr???

I know you're not supposed to use it on Vinyl and I have a roadster but have anyone of you used the product? I've seen it forever at stores and stuff, just wondering if its any good and what kind of results any of you might have had. So YAY or NAY to this product??? Supposed to last a year, highly doubt it but then again my car wax last 3 weeks at most. Supposedly polish lasts 3 to 5 times longer than wax.

 

So you can buy this product at Wally World huh, must be the $hit.
