I had painted the seats at one time but because paint doesn't adhere to plastic very well and the seats are Simi- flexible , the paint quickly cracked and flaked off. Power washing did the paint job in. I use these seat covers,

These covers have a small amount of padding which is nice. I cut pieces of 1/2" and 3/4 thick high density close cell foam then glued it to the high contact areas of the seat, under the butt bone, base of the spine etc., all those hard pressure points on my bod. By shaping the foam you can create a really decent form fitting seat .then slip the cover on. It made for a very comfortable seat for what it is.
