Flattening out the butyl as well with a small flat head once it's heated up helps to make sure everything is sealed up properly.

Also don't forget some small helper screws once the new lens is in. It will never seal like the permaseal did from factory, needs all the help it can get.
Some good additional info. I might add 4 tiny screws or some small clamps to the housing for good measure, thanks for the suggestion.
