If you want your Singer Featherweight 221 powder coated the process is long and requires the disassembly or the complete machine. Then paint is stripped completely by chemical, sand blasted. Then the process begins with applying the powder electrostatically, Heated to 400 degrees for 18 minutes. Now it is time to reassemble parts and Clean bushings and set the machine back the factory specifications. The Price is $1000 if you break down the machine or it is an extra $200 if you want me to take the machine apart and reassemble.
