The only purpose of the nail is to hold the wood while the glue sets. So why wouldn't this work?yes and no. The max length on the 18g nailer is 1.25, so if you're working with .75 in MDF, that's a little short. Regardless though, this is a great deal if you're on the market for some trim nailers. I'm thinking about picking them up to add to my existing PC trim nailer and stapler.
