I'd question his definition of 'glazed' to be honest.
I've never read it as 'something deposited' merely as leaving the object with a glass smooth surface as a result of frictional contact which may be either beneficial or detrimental, (Brake discs for example).
I can see some point to what he's saying but how often is a re-ring a simple and straightforward re-ring? Typically it's required for a reason and that relates to needing a rebore to a larger diameter. The only time I could see this applying is if you'd stripped the head and barrel and replaced the rings as a matter of course, in which case I wouldn't consider honing anyway, if the bore isn't damaged, enlarged or scored, why would you?
In my case for example, I have light scoring fore and after of the barrel from a partial seizure, without honing to get the whole thing even i'll never get a good ring seal again.
I'd love to know also, how can lapping in valves possibly be detrimental? I was always of the understanding this was to ensure a perfect mating face as cutting alone cannot guarantee this.
