Nike just built a ramp near our town with just standard treated plywood and it is warped completely. Each transition feels different; somewhat bubbly and slowly the the plywood seems to seep deeper beneath the coping. I was just making reference to woodward's use of skatelite on their outdoor...
Yes!! is it a mini-ramp or a quarter? If this ramp is going to spend alot of time outdoors I highly recommend using a layering of skatelite or masonite, besides both will make the ramp smooth as butter!
