It takes very little plastidip to do the grills, I think I used about 1/4 can on mine if even that much.
Prer work involves cleaning and drying them that's it really.

I wrapped the top piece on mine to match the paint a little better.



Plain black will leave you with a Matt look, or you can get glossifier and one coat of that will leave you with a satin sheen and more coats will turn gloss.
