Thata it?!?! Just multiple passes? Wow. I thought the helmet was 100% titanium steel and you went through hell and back, and then after serious depression, repeatedly hit your head into a wall. That looks so good! I wish my process of running and stomping rocks into my foam turned out good like this! But now that we have lavarock....(sharp like glass and pokey everywhere), maybe I can do something "natural"...For the deep scratches i use a Dremel tool and grind them into the resin.
