In two decades of work experience, he has never had occasion to rebladdificate a ball signed in silver? Forgive me if I'm dubious.

If it is indeed his first time experiencing this, he should be very open to offering you something (and something more than a refund for his work).

It's basic knowledge that applying liquid to ink can often meet with disastrous results. It's his business to know this. While signed balls may not be the majority of what he restores, you had better believe he has had his hands on a ton of them in 20 years. Even if he has a website with properly stated verbiage, I really feel he would only get off the hook if there is any sort of fine print on a submission form which you signed.

On the flipside, I do feel that it's the customer's responsibility to ask a lot of questions in addition to the restorer's obligation to verbally state or re-state if something potentially hazardous was being used in any process.
