The wow factor from these machines is when you put in a filthy part that has been buried in a thousand years of dirt, grime and grease and later removing that very same piece from the Dana-Ridge unit and it looks better than it did the day it was made. Having seen and worked on these machines for many years I still get surprised with the quality of the finished product. Imagine what your customers will think. They’ll assume you have a big green time machine that takes components back to the very day they were assembled.
Some of the guys that deal with vintage components would shudder if parts look too ‘highly processed’, but with a simple abrasive swap and ‘presto change-o’, a less bright finish that makes the component look like it did all those years ago without making it look too modern and of course not damaging irreplaceable parts as occurs in a dry process.
