Can I use a polyurethane finish for my outdoor pergola or arbor?

Question

: I just bought a brand new pergola kit from SimplyPergolas.com, and now I'm looking to add a finish to the wood.  I'm used to working with indoor furniture and woodworking and use polyurethane on most every project that I work on.  I'm wondering if polyurethan works for an outdoor project as well?

Answer

: That depends.  Read more at the blog of Simply Pergolas...
