Where can you buy HVAC putty?
I've posted this under another thread and haven't been getting much success. I need to know where you can purcahse HVAC putty (not mastic or cork tape).
I've already checked a half of a dozen Home Depot and Lowe's and they don't carry it. www.uri.com usually has all the HVAC supplies I need just not this!
Any links or store names would be appreciated!
