Let me say these are not the best overlays but sometimes are the only option. I have done several of these and here is what I've discovered. The vinyl is very easy to stretch. If you stretch it during install it will wrinkle over time. You have to try and get every drop of water out from under the overlay or it will cause problems. I always sand the original PF smooth and apply Rustoleum Acrylic lacquer and let cure several days before applying the overlay. Once the overlay is applied it needs to set several days to a week before repopulating. Don't overtighten the posts. The last couple I've used the clear playfield protector and had great results. I have never cleared over an overlay because I am suspect of the ink and figured it wouldn't hold up to the clear. I have seen ones that are cleared but never tried it myself.
