For BBO I wrap the lams in shrink wrap to hold everything in place and to minimize glue running all over...Then I wrap the entire thing in inner tube stretched tight....paper thin glue lines, and no boogers to clean up.
Oh ya, I also lay painters tape or packing taper on the back of the boo first to keep the glue from setting on the back. it minimizes trying to clean up excess hardened glue fron the boo backing.
