Interior dash trim touch up/restore

I know this is an old thread, but I am in the process of doing this myself. I tried with the silver pen trick but that was reeeealy hard and nerve-wracking. I also found that it did not stick very well. Now I am back to what I began with. Is there any other way to do this. I want to paint both the silver and the black. I'm thinking spending a lot of time masking and spray both the silver and the black.
