Cut insulation to fit openings, corners, and projections precisely and to produce edges
and shapes complying with details indicated.
Rasp or sand flush entire surface of insulation to remove irregularities projecting more
than [1/32 inch (0.8 mm)] [1/16 inch (1.6 mm)] from surface of insulation and to
remove yellowed areas due to sun exposure; do not create depressions deeper than 1/16
inch (1.6 mm). Prevent airborne dispersal and immediately collect insulation raspings or
sandings.
