I normally use straight MEK for cementing. I also have Plastruct Bondene for things I need to set faster, both have the same problems.
I have no luck cementing Plastuct Styrene, it might hold but there is no strength whatsoever. and usually it winds up breaking off. I have even sanded it first in case there was a release agent or something preventing the bond.
My second problem is with small diameter rod and half round from Evergreen. This problem is when I try to cement a tight curve the styrene will just snap when the cement is applied.
Any suggestions on either problem?

As for the small styrene rod snapping when MEK is applied , it is very frustrating . I've started to use small dabs of super glue to locate the rod in position , then go back afterwards with the MEK to permanently bond it in place . This seems to solve the problem , maybe since the rod is already stressed and set in place before it is applied .
I hope this helps .

I use testors tube glue for evergreen and dont have problems, maybe try that and see if it helps
I use Testors glue in the orange tube for everything l do works excellent...
*shudders* Oh man that's nasty stuff. Switch to a Zap-a-Gap type CA glue and you will never look back.
The Plastic Weld from Plastruct does work well with Plastruct products but it does take time. I think Bob has the right of it though. Tack it front, rear and in a curve with CA glue and use the solvent for the rest.
