In making any kind of outdoor pieces with cedar, do I need to be worried about brads (or other nail gun fasteners) eventually leaching rust, stains or simply failing? I will also be using waterproof glue in my joinery. I cannot find anything (at Lowes any way) that is labeled as a "galvanized" brad or finishing nail. Am I over-thinking this? I did find at Amazon galvanized brads and pins! Should I use something like this vs the stock pins/brads?
This will be a cedar trellis using half lap joinery throughout. Do you think that for the lattice section with 3/4 wide/thick pieces joined with half laps throughout I could use a combination of waterproof glue and pins vs brads? I just love my Grex pin nailer and they do hide well. I see that Grex has galvanized pins too.
