You might want to give this a try I have had good luck with Top Flight LustreKote its fuel proof and it held up pretty will.
I used masking tape to tape of the area to be painted then I sanded the surface to be painted with 200 wet or dry sand paper I wiped the area down with alcohol and then a tack rag to make sure it was clean. I used tin coats of paint till I got the desired results. This finish held up Ok for about 2 seasons.
