I am going to do mine in cerakote. Extremely thin and impervious to chemicals and Extremely scratch resistant and heat resistant. Only issue is nothing sticks to it, ie paint markings, unless you sand it. Going to us dp 90 as one application base coat the cerakote semi gloss black. That should leave all factory metal striations visible. Going to do all semi gloss black parts that way. Just what I'm doing, doesn't make it gospel. Going to do some parts in steel color as well.
Dan in kansas.
