Making an emergency repair in a Microchannel aluminum coil using Solderweld's Alloy Sol

Making an emergency repair in a Microchannel aluminum condensing coil using Solderweld's Alloy Sol. This model York unit is known to rub out like this. We quoted up a replacement coil, and replacement fan motors for this client, but they needed this unit back cooling ASAP so we had to make a repair. This was our first time using the Alloy sol product.
