No pics due to the large amount of dust stirred up, as well as lack of progress the last few days.
It's cold here. Real cold. Too cold to paint, too cold to use the filler I need to fill some holes on the backboard, etc.
I am probably going to bring the backbox insert and the filler inside tomorrow and let them warm up and then apply the wood filler once they are all warmed up. The initial sanding is done, the backboard has been vacuumed and tack ragged etc.
