Old-school rust removal, redneck engineering edition. 1970 Arctic Cat snowmobile gas tank getting de-rusted the slow way. Tank is cargo-strapped to the rear wheel of the four-wheeler, quad’s jacked up so the wheels can turn nice and slow. Chain inside the tank does the dirty work—knocking loose 50 years of rust without cutting or chemicals. Sometimes the simplest setups work the best. Watch it rotate and do its thing. #CrankinCramers #Snowmobile #ArcticCat #OldIron #RustRemoval | Crankin’ Cramer
