I would never turf rails again just turf the top where you need it.

never seen it a problem so long as the holes from the OE rails are filled....
it stays on great if you put on a coat of glue , and let it dry COMPLETELY and then put on another coat of glue let dry and install.
I think they look so much better turfed
Black ski with black turf looks great if you ask me !
