NorthWest Indiana | I paint the inside of my gravity boxes with a graphite paint to ease the unloading process as it is very slippery. I have painted a couple of gravity boxes over the years and have had good luck sanding with a DA sander and wire brush (hand and on a drill/body grinder). Wipe it down with a tack cloth and then spray with non-sanding primer and then a good automotive type of paint. Inexpensive and decent paint sprayers can be purchased from the big box stores or like Harbor Freight. | |
