In reality with the APA (American Plywood Association) grading rules, it doesn't matter where it is bought = -- it will matter what grade it is.   I personally prefer using the "aircraft" grade Wicks type stuff since it = has uniform high quality grade of plywood throughout the section. Construction =   grade plywood (whether it has exterior face sanded or not) will have = lesser grade interior laminations (knots, and the like) -- which means when you = cut it, you may get a "ratty" edge if you happen to lay your cut line on that sort of interior "defect." While the outer lamination is nicer and more pristine, the interior lams or not as clean. I have made a cut, looked at = the edges with an oh-thats-not-very-pretty reaction, then tried another cut again.   The other stuff is much nicer and more uniform to work with. Anything I = have that will show, I really like to use the Wicks ("aircraft") stuff.   Have fun   Dennis
