Default Aluminum composite reportedly stronger, lighter than carbon

While it is not a technologically daunting task, it is not cheap for
larger mirrors especially when you consider shipping. I have a 17.5"
mirror that will need realuminizing when I finally get around to
putting
it into a scope. It has been cleaned exactly once, but the coating
is nearly gone entirely after 30 years in storage.

Offhand, do you know anyone who recoats mirrors that size?
