There is only one paint that will look like metal and that is Alclad. However, it’s very delicate and will not stand up to handling or any type of chemicals. It’s used for models to simulate chrome or natural metal finish.
Here is my 1/48 scale F84 painted with a base coat of gloss black enamel then Alclad is lightly misted to let some of the black show thru giving it depth.
You can see how good the reflective quality is simulating the metallic look very well.
Unfortunately, it’s very delicate and care must be taken when handling the model otherwise the finish will get ruined.
