I got my cowl back from the dipper and it was nice bright shiny metal! After cleaning the oils off with brake clean I orbitaled it with 80 grit and scuffed it with a red scotch brite pad. Then I masked it off where it will be glued/welded and put a coat of glasurit epoxy primer on it. This weekend I will remove the cowl from my car and clean up the lower cowl area.. Hopefully get it epoxied, seam sealed and painted, that's if I don't find any surprises!
