I have a 6" mirror from a Criterion RV6 that needs to be recoated.

I found a service that will give me a 91% relectivity for $30. Is this reasonable ? Should I get a higher relectivity ? Can anyone recommend another company ?

Thanks

$30 sounds like a good price. I have had a couple of mirrors coated here with good results:

I don't know if you could tell the difference for more than 91%.
