I question Geoffrey Brown's statement concerning the limited bond
strength of B-72 to a metal substrate.  In my testings this resin will
have more than adequate strength, even with use on dissimilar
substrates. I also question the "greater resolubility" of 3M #4475
Plastic Adhesive.  What is this material anyway, and on what grounds can
it be recommended?
