Hi toot, I like use a industrial etch primer first and before it drys hit it with the chrome paint and put it out in the sun to harden but it's not so good on mufflers ,looks good but flakes of after a bit. You can use an industrial etch primer and a good heatproof silver which gives a pretty good look aswell.close your eyes fastidious restorers , this is just to pretty up a little.
