I need to replace a section of my galvinized roof gutter. I was told
that the best way to join the galvinized gutter sections is to solder
the pieces together. I have soldered copper pipe a lot in the past, but
never galvinized steel. Is the process essentially the same as pipe? Do
I need to use flux (spelling) and do I use the same type of solder?

Thanks in advance for any responses.
