Hello, will this work to coat a steel surface? I want to silver plate steel headlight reflectors on a vintage car. Thank you.

Hello, the process you are referencing is called Spray Chrome. For this we recommend our Angel Chrome line of products. It is designed to be used as a first surface mirroring. To cover steel you will want to use our Metal Primer in addiiton to the base coat, silver, top coat etc. You can see it all here: https://angelgilding.com/angelchrome.html
