I use a brush, about 8 to ten boxes on my closet rod at a time.. It is a Pain.. I looked for that ECO wood treatment at the big orange chain store but they didnt have it.. would be nice to dip and hang.
I tried stacking the boxes and spraying, but if I do that it glues the boxes together, and popping them apart invariably pulls paint off, and sometimes a hit of wood, leaving a spot that has to be touched up.
If I ever get the new building we have been discussing the concrete pad behind it will CONSTANTLY be changing colors when I spray.
