Just finished laying down 2 coats of epoxy primer on the new Mar-K bed sides, front panel and tailgate. Getting closer to laying down some paint, probably over Christmas break. I am planning on assembling the bed sides and front before paint. But now I am contemplating whether to bolt the fenders (and steps) to the side panels before paint. I am not worried about rust because everything is coated in epoxy primer. And not really concerned about paint inside/behind the flanges and seams. I am leaning towards assembling everything before paint. It would certainly lessen the chances of any damage to fresh new paint during the assembly process. Anyone faced this situation? Any input on fenders on or off for paint?
