Hydroturf seconds are usually cosmetic blems. Not bad enough that anyone would ever notice but they can't sell it to retailers.
I have a rubberized factory sprayed liner in my boat. Not sure how it could be any heavier than any other full covering coating because it isn't that thick. No problems here from it being too rough but the harder bedliner materials probably would be. Even though it is OD green, it is much cooler than the same colored painted surfaces.
