Question about Optics
The ETX 80 is very difficult to work on. Getting at the flip mirror requires an almost complete teardown of the telescope and its mount. If you are not experienced at repairing the ETX scopes I would not advise trying this youself. I doubt that leaving the scope in the case too long is the cause of the coating damage. It takes years for fungus to really destroy coatings. I have seen newer Meade mirrors losing their coatings prematurely and feel this is a manufacturing defect. If the scope is in warranty it should go back to Meade. If not I'd have my dealer look at it and see if Meae will make an adjustment on it.
