My girlfriend bought me the Playfield polish kit for my birthday. I just have to say it works fantastic, I honestly could not believe how well it cleans and polishes the mylar and playfield.
My taxi had some swirl marks and what looked like cracks filled with carbon in the clearcoat. I tried to clean it with everything I could possibly think of, Mr. clean magic erasers, special wax/cleaner,simple green. they all cleaned it ok. But the maks were still noticable.
I used the kit, and it looks good as new now, maybe better.
My NBA fastbreak has a full playfield mylar, (I don't know why, it doesn't need it) but it was kind of scratched/dull. Now you can't tell its there. WOW.
Great/amazing product, if you haven't tried it, and you have some questionable looking playfields I suggest you get it, it honestly worked wonders. I just wish I would have taken before and after pics.
