Yeah, it didn't stand up to the heat on the carport. The ready room set is in an air-conditioned retail office space. Still, I thought about it a bit, and with some similar input such as yours, this afternoon I went with the vinyl soffit again.
Today I sanded the patches and primed them with Kilz. Tomorrow, we're going to start painting Starfleet gray!
One minor setback: the countertop we were planning to use for Captain Grigory's desk was found to be mouldy underneath, so we're going to have to head to Lowes tonight.
