I plan on drilling some holes in the bottom for water to drain. The rocker panels are all welded in, . everything but the outer body sheet metal had been media blasted and primed, I want to rough the bodywork and custom mods out first, then media blast the outer body when the car come apart for paint. This is really important because you want to media blast all your welds(even after you grind the weld smooth),then apply epoxy. If you don't the paint will eventally lift.
