flat black Krylon in a can. If you are just doing the sterns (and they are recesed like on my old 5.2) why go to all that trouble? I painted my 5.2 sterns with it and it looked great for years. The recessed sterns are simple to mask off (just run the tape around the outside) so even if it needs another coat in two years, it will take you 15 minutes and $2.00. After repairing a nearly dismembered stern on my 6.0NA (this stern is not recessed) I shot it with gloss Krylon and it's holding up fine. Would I paint a whole boat like that? Heck no. Sterns only? yep.
