I guess I made a mistake reading TCR and seeing a chip listed at $200 and assuming it wasn't that common. Did you look at the whole offering?

Some of them aren't worth the time, I agree. And that would be IF it was even possible to remove them.

Concrete is probably less invasive than some plastic that would bond to the surface. The water content and the heat in the concrete curing would be more of a problem. But the plastic also heats up as it cures...

Just fun thinking that it's possible. I'm forced to face the truth, doing the impossible might be a little harder than I thought! lol
