Removal sounds like a lot of work, I think it will be prep as much as I can from the inside and then up a ladder for a day for a couple of coats of the Zinsser All Coat. Realistically I don't expect to be more than five years (and I can't actually see the back of the house) so I'm willing to sacrifice perfection for convenience.
Cheers @Airhead and @Aunt_Maud
