I just recieved a mirror back from the following coating supplier and had excellent results, FAST service, and a good price (no I am not receiving any payment from, or am affiliated with this company in any way!) I am a satisfied customer, and very impressed with the advertised 1 ton/90" capability. Call them before you send your mirror, and they will give you a quote, and shipping instructions:
