LeftE, a Polish is a Polish? Well, I guess that statement could be correct but not every polish is the same. Every manufacturer uses a different type of polish, that is why you can't use different polishes universely and expect to get the same result. That is specifically why Brunswick came out with a factory finish polish, because the "out of the box" finish could not be duplicated with other polishes on the market. Just as Wells said, if a company makes a polish for their equipment, you are probably better off using it. (if you are trying to get the "out of box" back as the finish.)
So you think all the polishes are so interchangeable and the same? Well, let's put it this way, I haven't hear of anyone using Factory Finish polish on their car yet? But if you want to try it, I'd be curious to hear how it works.
