ATM Best Durable Coating?

[Dan Gray <grayarea@teleport.com>]

I've had a 6" cass for about 20 years, and have never used it.  Now I'm
trying to use it for a guide scope, but the optics need
re-aluminizing/coatings.  I know there's been a lot of discussion about
coatings recently, but I would like to know what is the best aluminizing
and coating that would last the longest.  Of course price and light
reflectivity are factors but not as much as durability.

Any opinions or help on the subject would be appreciatted.
