Re: ATM Mirrors - cleaning fluids

["Bill Prewitt" <bprewitt@neo.rr.com>]

One substitute for USP collodion is sold in an aerosol can, which makes it
convenient to apply.
It is Pre-Cote 33 Blue Spray protective coating from Universal Photonics, part
number LB0004
http://www.universalphotonics.com/

I've used it to clean my 20".
It dries quickly, then can be peeled off in large sheets which hold the dust and
dirt.

Like Collodion, the product is classed as a hazardous material, which makes
shipping more expensive.
The HazMat rating is:
     Health 1
     Flammability 3
     Reactivity 0
     Personal Protection "H"
