Removing screws locked with pressurised cockpit sealant?
Good Morning/Evening.
I have and Aerocommander 685 twin that I am turning into a simulator. Due to requiring access between the inside of the cockpit and under floor, I need to open up the floor. Most of the centre panels are merely screwed to the floor framework, but as it's pressurised, everything was sealed with some sort of sealant. I have tried drilling out and using an easy out, but my drills keep breaking or blunting. I got so deparate that I went at the floor and used cutters to tear it up. Problem is I still have to seal it.
Is there any way of dissolving this compount, whatever it is, or removing the screws. Any thoughts? Thanks in advance for any replies.
