Honestly for the effort involved just take it to the pros. I got all my strikers for hood , doors, trunks, ashtray, gas cap and ring plated for 40 or 50 $ locally here in Ottawa. I chose yellow for half the stuff and silver for the other half. They first acid dipped to remove any dirt and oils then gave them back to me just asked me to wire brush and clean off any paints to bring the cost down. I feel like getting everything zinc plated
