Default removing mylars at every annual?

If you have proper sealing, teflon tape under mylar, it is not possible to lubricate hinges. Use upper mylar to prevent water or dust entering hinge. Change everything after 3-5 years and lubricate using grease, not anything that comes out of spray can as it is only cosmetics.
