On a forage at the local hardware store I saw cans of gold and silver spray on chrome and had a flash back to 1981 when as first year apprentices we asked a tradesman into modding cars his thoughts. Have things improved in the last 25+ years? Why did I bother remembering that after all these years? Google shows the American brands using a black base coat, followed by the chrome, buffing and then clear coat on the top. White Knight which is I think the brand at the hardware store is more like slap it on as long as you do minimal prep and have same undercoat/previous paint with no mention of buffing or needing clear coat, it is mentioned that you can clear over if you want to. While I like the minimal effort for maximum results approach I have a feeling White Knight are telling fibs about the results. I would think buffing then clear coating would give the best result?
