When I painted my 84 in charcoal hammerite it didnt look very good at all when I first started. It eas just a normal charcoal color. Then I wasnt paying very close attention when I painted a fiew strokes and it hammered right before my eyes. It took me a moment to realize what I had done. I had painted it so thick it was almost to the point of running. So I repainted the parts I had alread done and it looked great! It is very tricky to get the effect to come out even but it can be done.
