Sounds like whatever you''re cleaning it with is attacking the plastic. If it''s as "greasy" as you say, paint''s either going to peel off and never grip, or bond totally to the chemically receptive "greasy" layer. You might as well paint it and see. The worst result would be having to replace the cowl, which you would have to do anyway if it continues to deteriorate.
