Ok here's what I found. I used a surface cleaner made by sikens (I'm sure other paint manufacturers have similar products) and after wiping it on with a cloth to soften it up I used a nylon pot scrubber pad. In 1/2 hour I cleaned around the window openings and 1/2 the roof.
The glue just clumps up and is easily vacumed.
By the way my paint guy wasn't too fond of the WD40 idea, something about residue in the seams mixing with paint prep.
