1522 is a soft plain open weave surfboard 4 oz that is also loved by model builders. The A218 surfboard finish is one that we sell a lot of to model builders that is soft enough to do the job. 1522 finished in Volan would be somewhat softer but very little is woven or that makes it to us anyway. Being the open weave it is the A218 finish works pretty good in being soft enough to conform to pretty intricate areas. All rolls are rolled on 2" pvc and carefully packed as usual.
