Thanks for the advice, i didnt know about the topsheet incorporation so i had to take a look atthis particular board and its truly cosmetic. but sweet on the heads up because if it had beenpart of the strength i might have seriously done some damage.this is an old k2 dart, and its a wee bit thicker than todays boards so ill be ok with the sanding,im only going as deep as the gashes from where other people have ran their board over it.i was talking to a paint shop guy today about a flex agent that can stand freezing temps andstill have a decent amount of flex, so im pretty excited about this!ill post pics of the progress 🙂
