How many of us are there? Owners of Dodge based RV's?

You're supposed to use it, not wear it. If you think pipe dope is bad, you haven't lived until you've tried working with Tremco Acoustical Curtain Wall Sealant. (aka 'black death')

As for pipe dope, I usually forgo the brush attached to the cap. Instead, I use an acid brush, dipping it in to get just enough dope on the bristles to do what I need. (And, throw the brush away when I'm done.) A little is good, a lot is a mess waiting to happen. (As indicated previously, only on the male pipe threads.)
