Hello, has anyone any experiences of peelable mask on MacDermid Sterling Silver coated FR4 boards?

We have just been going through the process of changing our board spec to silver coating for all, but the peelable process seems to give us a bit of a problem.

AFAIK The peelable goes through an oven to cure it, which seems to tarnish the silver.

Has anyone any recommendations/suggestions that I can pass onto our supplier
to allow us to have our boards that use peelable silver coated too?

Thankyou,
Matthew Lamkin.
