Don't think you can thin epoxy putty very easily, but I could be
wrong.

T-88 is listed as a structural adhesive on the SO-3 web site which as
you say makes it a different animal from laminating resin.

I've always used laminating resin as a "glue" or thickened with
micro-balloons as an "adhesive" with success, but then again,
different horses for different courses.
