Window trim trimming.

Thought I would share what I learned today about cutting aluminum window trim. I ordered the 1 1/4" door thickness trim and later decided to go with a 3/4" thick door. What worked best for me was to use the angle gringer at 45 deg on the edge and then peel the flange off like a sardine can.
Now a question. I'd like to put the windows in without screws. What would be the best adhesive to use or should I give up and just screw it down?
Thanks.
