Weld-on cement

[SharpsShooter]

It's difficult to obtain Weld-on 16 up here in northern Canada, so I bought some off of E-bay. Bought 2 tubes of it, it has arrived after the customary three week delay with anything bought online. The problem became apparent when I opened the package, seems the seller had only one tube of Weld-on 16, he substituted the other for a large container of Weld-on #3. Is Weld-on #3 useful for anything related to building a guitar? It states on container "Clear, water thin, very fast curing cement. For Joining Acrylic"

Thanks,
Brian.
