Robbo, I was wondering the same thing about paint. It should be exterior, at least on the outside. I was considering using my excess paints to paint the inside. It would be nice to do the outside too though since we already have more than enough paint. Its just that it is interior.
So painting the interior would be okay? It would be painted weeks before anyone moved into it.
That would be fun! I did a wall of my room a bright orange and that is what I have left over... a lot of it, lol.
