Here I have the under-porch area of the exterior walls sided, and the porch with trim is dry-fitted on: One can make out some rafters (skinny sticks)-- I spaced them such that they'll make convenient hanging points for a porch swing... So I put the first coat of exterior paint onto the siding: Left w/ flash, right w/o. Hmmmm... I'll see how it looks with a second or third coat...
