your main thing is the raw plastic cargo carrier. you need to spray some sort of plastic adhesion promoter or plastic primer. first before you spray any type of paint. some rattle can paint have it already in .And yes clean it with soap and warm water and a red 3m scotch brite pad is correct.What has been your success on painting the "Sears Cargo Carrier" on your HF frame? Rattle can, brush, and paint type? Comments welcome.
