Hi, an aluminum porch gutter leaks at a 45 degree angle. I'd like to try
to fix it by applying caulk inside the gutter at the 45 degree angle. If
this is a good idea which caulk should I use?
NP1, not NPI. http://www.bestmaterials.com/detail.aspx?ID 136
Make sure you clean the inside of that gutter perfectly and remove all
of the old caulking or you'll probably be doing it again before too
NP1 is a Sonneborn product. It is a one part polyurethane product
and is excellent.
For the gutter, I would recommend butyl rubber, sometimes sold as
gutter and lap sealant.
