I boxed in some basement windows in a very not-square house, and there are
some gaps between the boxes and the casing molding that rests on the sheetrock
walls, some as large as 1/2". The homeowner would prefer the gaps filled in
and smoothed out rather than me laying a piece of molding over it. Since the
gaps have no bottom, I thought I'd create a bottom with some minimally
expanding foam and then fill the remainder with Bondo. I'm sure caulk would
require many layers to stop shrinking, drywall mud would crack and wood
filler...no idea but it has never worked well for me in smaller
applications...
I'm open to the more experienced options before I revisit this brain cell
massacre of my teenage years.
thanks,
