I've picked up a few different wetsuit/neoprene cement products. If you need names I can see what they are. Not very expensive and can be found easily at some shops and on Amazon.
I second the last post about avoiding chemicals that aren't guaranteed to not hurt your skin. Do you want your boys getting rashed just from using the wrong wetty product?
^+1 I used a neoprene cement as suggested by walkingonh2o. I used a product by "block surf" available from my local surf shop and it has held up fine. It works like contact cement. Put it on both sides. Let it cure for ~5 minutes, then press together. Read the instructions, as your product may differ.
