Ben Davison –
Excellent flux that works well on copper and galvanized steel, both clean and when oxidized. Washes away easily. My go to flux for the repair and small scale flashing fabrication work that I do. Shipping from Stortz is quite expensive ($23 for $48 in product) but they are otherwise really great to deal with and I really appreciate their hard to find tools and consumables. Also their instructional videos are wonderful.
