Seal with "Great Stuff," eh?  Bad idea.  Although you can buy this product at
any good hardware store, it is seriously hazardous.  It releases isocyanates
some of which have a TLV-TWA of 0.005  ppm.

I did a pro buono workers' comp case for a non-union scenic artist/prop maker
who was disabled by the stuff.  She developed isocyanate asthma which is
usually fatal in time without further exposure to isocyanates.  She used Great
Stuff to repair the "Audrey" props from Little Shop of Horrors.   In her
thirties, her life is essentially over.

We also have two other scenic artists in New York and two more in Chicago
whose careers are severely limited by their sensitivities to isocyanates.

And don't be fooled by the MSDSs which say the isocyanates are "prepolymers"
that are unregulated.  In the UK where they have more shmartz than we do about
these things, they regulate isocyanates by the number of reactive isocyanates
in the compound, not what the isocyanates are attached to.

I know most people can get by with using this kind of stuff for a while, but
I would never suggest the use of this product.  If things go wrong, they are
not fixable.
