We wanted to run headset wire to the rear seats and refresh the interior a bit. Read Bruce's guide, bought cans of SEM cleaner, paint, this, that and the other things. Pulled most of the interior and had to go get the real masks due to the amount of mildew in the foam used for insulation. Looks like SB-208 time. Here come the questions: - What is the trick to remove the two (?) roof plastic panels? Can't seem to figure it out, and don't want to break anything I don't have to, but I do want to clean / paint them. - The primer on the steel frame is flaking off; I plan to clean it all up with steel wool and apply epoxy primer. Will that work? Any tricks to get enough of the primer on the outside parts of the frame (blocked by the aluminum skins), or just a small brush and lots of patience? - Is "aluminum tape" we're supposed to use instead of duct tape the stuff they use on chimneys, etc? Looks like the kitchen stuff on a ~1" wide roll, with some glue on one side. - What do I use to replace the fiberglass with, and how much of it do I need (whole plane, firewall to baggage compartment)? Thing is, I'd prefer to source something locally than wait for a shipment from a MSC, Spruce or another US source, but if I must wait, I will. From a post by @PT20J I understand the stuff from Mooney is closed cell soundproofing foam from Buckley + mylar, someone recommended SoundEx from Spruce, but I can try to source some "Ensolite" (or equivalent) and run with that, correct? Asking, because Ensolite seems to be a US trade name and we likely call it something else here. - 208 says the new stuff is not supposed to touch the steel frame - does it mean I glue it to the skins? Use the 3M Dual Lock stuff? Use aluminum tape? What else do I do, if I'm this deep into the plane? No new windows, but I'll tint the ones I have (thanks @Skates97) but if I can source parts needed to do something that makes sense in reasonable time, why not.

In rectifying some of the few deferred maintenance items on my 71 M20E, I elected to remove the foam that had been installed to replace the fiberglass as part of the guidance in SB208. However, the foam installed in my airplane was not the Mooney kit but rather a black/gray self stick foam. While, I had not though to grab pictures of the foam before I removed it, the foam looks extremely similar to the foam featured in Mark Gunnison's youtube video (I believe I have dropped it in with the correct time). Upon removing this foam I found that it has reacted with the existing green primer (Unknown if it is original), wherever the foam was attached the primer has cracked and flaked off creating some minor general surface corrosion with some deeper pockets of pitting on the aluminum surfaces. The panel worse effected where the baggage compartment bulkhead, which was peculiar to me as their is limited ways for water to find its way to that panel. Working with my A&P we have a solution which evolves removing the effected primer, using scotchbrite to clean up and remove the corrosion and then etch prime all effected areas. Has anyone else experienced this? Has anyone ever looked behind the self stick foam? I already have the Mooney SB M20-208B foam kit but is their any reason to look at other options? I know I am posting this without pictures but left my camera at the airport. Should have pictures by Thursday.
