My Savage 11 Trophy Hunter, I did using Krylon Fusion paint, Rustoleum plastic primer as a base coat, Krylon Clear coat(8 coats), Fish net hose.
Denatured alcohol ,for final cleaning, after 600 grit wiping, and soap and water.
Let every coat dry for 1 hour. Do not sand between coats (unless you leave it 24 hrs), each coat must be very light coats.
After 14 days of curing, wax with Johnsons paste wax and buff.
Very tough and resillient, no more of a problem than wood or any other finsih, if you bang it against a car door, it will probably chip.
Heres my grandsons Cricket, just for fun. He calls it Copperhead.
