guys, thanks for the tips on taping the lines. ive read that before, but still am unclear on how close you guys try and get to the tape. it seems if you touch it you will start to fold an edge (probably not a big deal).
do you do the same for all of your blockings? rough? high build? final fine or wet sand prior to base?
and, is this normal? straight edge from one end of the door to the other. its a gradual dip, and about the same on both sides.
Thanks, Tim
