I have never used Weldon 4 before, so I can't really say. You're just trying to seal acrylic to pvc, so whatever Weldon would recommend for that.
Thanks for your reply. The weldon 4 worked perfectly. For future reference, the only difference between 3 and 4 is the amount of time you have to work with it and the curing time. 3 cures faster than 4.
