We have large 250 gallon tanks that are 36" wide x 48" long to be able to handle a big variety of part sizes.

For starters - we know how important your parts are and we will take good care of them and service them with great care. Gentle handling and thoughtful packaging are a part of the process.
How do we turn them black? The process is fairly gentle and adds virtually zero thickness to your part. In a nutshell, all we are doing is cleaning them off, rinsing the soap off, dunking them in a heated salt bath that converts the iron into a naturally occurring black iron oxide, then rinsing and adding a final supplementary finish.
See that's not so bad, right?
