From IPS page :
5 - Water thin, slow-setting solvent cement for bonding acrylics. Also bonds styrene, butyrate, PETG and polycarbonate to themselves. Will not bond to cross linked acrylics.
Since annealing is not an option for the average person, a slower setting cement should help. Weldon 5 is more expensive, but you also get a lot more.

Can you send me the link from that Page? weird IPS would say that and the weldon page its self doesn't even mention acrylic under 5 and in fact points to extruded plastics not acrylic.
as for crazing, I think this is a rumor created from companies trying to justify there price of there products because the chose to go with cell cast for better looks. extruded doesn't crazy because of the glue or because it is extruded, it crazes for the same reason as cast, stress points caused by gluing edges that were not done properly or precise enuf. the major cause is using the wrong types of blades to cut acrylic, not getting a flat edge and flame polishing.
