There has been some complaining about dimpling and the like with kevlar construction.
More to the point, anyone who saw Gordon's A cat split in half might be interested.
I don't think that has much to do with the Kevlar...rather how MUCH kevlar was used and how well it was bonded to the core. A fiberglass boat with a thin skin will dent just as easily if not more so.
