Quoted from swampfire:I'm trying to understand this. Wouldn't a harder and longer-wearing surface provide better protection?
Simply put.. what they are striving for with a car isn't necessarily the same as for a pin.
First, there is the topic of how they bind/adhere. For games with modern clearcoat it shouldn't really be an issue given they are basically using auto-clear these days. But mylar, decals, bare paint... those are different applications.
Second, there is the issue of the carrier/suspension/delivery and any interactions that may have. This has seemed to be a non-issue for most people's experience. Again, if your game is modern cleared, less risk here.
Third, the issue of hardness/slickness. You don't actually want a perfectly smooth frictionless surface... you want the ball to have some bite so spin/etc comes into play. This is the same issue many people had with after market clearing for so many years. The games play different (and not necessarily better) when the surface loses all it's bite. These polymers actually strive to form slick, hardened barriers to protect what's underneath.
Lastly - how they are cleaned/removed. Removing these layered products when necessary can be more convoluted vs a straight forward wax. This dovetails into the issue of just how clean your game is before application. With car paint finishes, we strive to make the finish pristine and free of all contaminants before we apply sealers/protections. When you're just wiping down the game (especially without stripping the game) and putting on a top coat of protection.. you're not getting that same level of clean before you are applying your protection. The polymers work to create these hard seals designed to never leave. Wax is more your 'disposable hero' and there is less to worry about trapping stuff with it... wax will wear out and is stripped easier.
If you want to concoon your game.. clear it. Don't use a product intended to layer coats to provide environmental protection. My opinion... YMMV
