Awesome job and color on those cranks! Do you mind sharing how you were able to maintain the 'Shimano' logo for the final result? Would love to see a how-to video in the future!
Sorry for the slow reply here but honestly I just got lucky that the logo was still there after the ano shop stripped and re-anodized the cranks. If it went away I was planning to use our laser etcher to etch it back into the cranks though.
