I am wondering if anyone knows af a Mirror Coating Service in the Los Angles area? I hate to have to drive all the way to the Bay area for AlCoat.

Reposting this from my reply on the equipment talk forum:

Precision Applied Products. They have a website: http://www.precisionapplied.com/

They coated a 10" for me a few years ago and did a very nice job. Good service, quick turnaround, and they did the secondary for free (just put it in the chamber with the primary). They are located in Placentia, a suburb of LA.
