So what do you guys prefer to seal your joints? i like either Dap or Liquidnails, and maybey some silicone. (a nice coat of resin alon the walls helps to dampening against air leaks i've heard)
Because I have a table saw I just glue everything together. The glue acts as a sealer. Now to get realistic, not everyone has a table saw. A thin bead of silicon sealer (instead of glue) will work extremely well. Just make sure it says 100% silicon.
smooth seams...no sealant is necessary as Ranger said. Glue is enough. I use glue to seal the joints too though.
