This is a true triumph of engineering over deterioration: in this YouTube 
a dedicated lover totally restores a vintage Triumph Tiger Cub motorcycle. Sure, a number of parts were beyond repair and needed to be reordered or fabricated, but the end result is flawless. Of course this again requires some special tools, like the fact he is using special high temperature paint for some parts, because they operate at high temeratures. And of course he polishes after painting, for that perfect end result.
