I just did mine with the plasticote ceramic stuff. Easy to use looks good, once its cured real good gas don't bother it. But it takes a long time for that I did a water pump cover with a textured black when I did Grks engine . I got it out the other day and rubbed it with premix and nothing. Then tried lacquer thinner the thinner finally bit in and removed it, but the premix never touched it. I think that would be the ultimate for durability hiding and retouches. I'll take a pic of the can and the part later.
