life of applied primer coat (MIL-23377) when being exposed to environement and sunshine
(OP)
we have an aircraft that is to be preserved for some time in future. it was depainted for inspection. It has presently been primed with MIL-23377 primer.
the aircraft will remain exposed to UVs and sunshine alongwith rest of environmental factors. i do know that a top coat will endure around 4 years ((in case of parked outside) and 8 years (in case of parked inside)as indicated in USAF TO 1-1-8.
what life can we expect this coat to be of, while in open and in shade?
thanks in advance.

Yes, higher thickness usually improves corrosion protection over time. But that seems to be secondary to the issue here regarding epoxy-based coating exposed to ultraviolet radiation. The coating will be damaged and not prevent moisture penetration.
