Are these a decent product?
How are they applied? Do they come in several pieces and I have to match the seams? Or do they as one piece? Is it hard to keep air bubbles out when applying? Do they stay attached and unfaded?

Thanks

the overlays are good, it you have time just take your time and there will be no air bubbles, they dont fade, they com ein one piece or sometimes 2 depending on what style you get etc..you can ask bluebatmobile if your in so cal i can do the install for you etc.. let me know
