[corecoatings]

Chrome is pretty interesting in that when you do the first coat you can practically wipe off the "chrome" with your finger. From my experience , if anything comes out half decent the first time around "god willing" a light coat of clear can only protect the base coat chrome or any other powder coating color I would guess.
Experiment, maybe power wash all the grease and you can and give it a light hand sand to knock loose the potential failure spots then clean it again and shoot the chrome. As long as it has some tooth and is relatively flat you could work around stripping it. Take care
