Sorry if I missed the info from this thread, but did you mention what your primary mirror was made of? You may be worrying needlessly about damage to the figure of your mirror when the SiO coating is removed, because it depends what the mirror is made of. Plate glass is a problem, but boro-silicates like Pyrex should be OK. This info I received from a reputable optical expert,

Good luck,
Nick
