Using 1 shot lettering/stripeing paint will work just as well.
It should last a fairly long time if you like hand rub the area with rubbing compound before applying the 1 shot paint. This will help clean any polish , or road grime , and such.
Then after a week of dry time you can go back over it with a good polish to help seal it off.

I usually forget about hand stripeing as I always use an air brush or paint gun, my hands areant as steady anymore ,a straight line would end up like a
EKG line ...LOL
