When having professionally done a frame off restoration of our 300 B, the only thing that stood out in my mind was that the stainless trim(there is a lot of it on these cars) was not the the top concours standard of the rest of the car.
After living with it a few years and considering various very costly options to remove, polish and re-install the stainless I decided to do it myself, even with my extremely limited experience in such a formidable task.
Acquired a top level Baldor buffer and stand from Eastwood along with various sanding papers, buffing pads, polishes and various books on the topic,,,,this in the pre-tube days. U Tube offers is your friend today.
Removed all the trim, set up shop in my driveway,,,you can really dirty up a garage and must be aware of flying parts as you learn.
Some 6 weeks and 200 hours labor and learning and re-doing, I was done and extremely pleased with the outcome. Often at Concour events and other such car shows I am asked who did the car's stainless and can I give the phone number.
Give a man a fish, he can feast today, teach him how to fish, he can feast for a lifetime.
The skill I learned(Not the best but pretty darn good) i have often used over the years to my great advantage and satisfaction and of course my pocketbook.
Reno340 has it completely correct. You may surprise yourself as I did.
However if you still decide you must pay someone to do it, do not try to cheap out. There is much 2nd and 3rd level workmanship out there. Poor level stainless just as with poor chrome can severely compromise the best body and paint efforts put into a car. Go to some events and closely examine the stainless on the cars, you will rapidly learn quality.
