About a third of the exterior of my house is very rough stucco wall. Thick
nap rollers are necessary to get into the nooks and crannies of the stucco.
The rollers splatter a lot of paint everywhere and require a lot of elbow
grease. I have been using those little 50 cent disposable foam brushes for
some of the finer work (near trim). It occurred to me to try a large foam
sponge.

Has anyone tried such an approach?

Does anyone have a better suggestion?
