I just bought a Bostitch 15 gauge finish nailer for some exterior trim work. Bought some Bostitch nails. They say they're 'coated.' I emailed Bostitch and they say the coating is not galvanized but just a glue coating that helps in removal. They said to use stainless nails for exterior.
Unfortunately the stainless nails are 4 times the price.
I presume I need galvanized nails for exterior work, right? I'll be using this with both wood and PVC trim.
I may just return the Bostitch and get something else for which galvanized nails are available.
