We make parts and mainly use a fairly hard nickel silver alloy. We put stainless steel on our guitar models, with the exception of remakes 49-50, where we adhere to the rule - to use materials of that time. But I need to devote more time to working with the CC. You are right. I need upgrade my tools box a little. )We use stainless frets on all of our builds by default and have never had complaints, only the opposite.
In all honesty the cost is not much more either and it’s a great value for the customer to not have to worry about frets for life. It comes down to what tools you are using and if they are quality tools like others have said you won’t have any problems.
