I went the full disassembly route (removed needles) and got all the green film off without a problem - until I re-assembled. The gauge needles do not work the way they used to and that's with re-installing and calibrating them as detailed earlier in this thread. I'll try again tomorrow but I think I'm screwed. My guess is I'll have to try to get it covered by Subaru by putting everything back like it was and saying... "it's not working right". Just do yourself a favor... don't remove or significantly disturb the needles.
