Two Part foam pour

[Royal]

has anyone use two part foam to pour into an empty fiberglass wing? Or is it to much pressure?

Not practical.   No way to determine the expansion and the foam can be very porous.  A long airfoil could have voids.

i used some minimal expanding foam around some house windows and they are so tight I can barely open them       😞

Be nice if this worked.

That's to bad. Maybe someday they can get a good two part foam to do that in. Would be amazing and fast to do.

Dark aero uses this method for their wings. Be nice if they could do something like this for the EZ.
