Model Railroading > Cement for Walthers Structure Kit?Date: 09/09/19 16:01 Cement for Walthers Structure Kit? Author: bioyans Hi All:
Quick question, regarding the best plastic cement to use on a newer Walthers structure kit. Started assembling their 933-4036 Rail-to-Road Aggregate Transfer kit (HO Scale), and found that my bottle of Testor's plastic cement (liquid) had no affect on bonding the pieces together. Even after a few moments of holding the parts together, applying cement to the joint from behind with a brush, it failed to bond the parts. They simply fell apart, as if nothing stronger than water had been applied. This is the first time I've ever experienced anything like this. Testor's liquid cement always worked well in the past. Granted, this bottle is old and near the bottom (leaving lots of air inside when closed) ... but would that have any affect on its ability to bond styrene together? Other plastic kits seem fine. Has Walthers changed the formula for their plastic? Any ideas on a cement that is more effective? Thanks in advance for any help you can provide. Posted from Android Edited 1 time(s).

It DOES take a while to set up compared to my usual (Ambroid or the recent MicroMark copy). As the poster mentioned above, you can use ACC ("super glues"). Some major joints benefit from the classic Testors Glue (like the stuff we used to get in a tube). It takes a while to set but I have had good results with using it for major assemblies (walls, roof, etc.).

May try a new bottle, and see if that works any better. Posted from Android Date: 09/09/19 17:02 Re: Cement for Walthers Structure Kit? Author: map Ambroid Pro Weld was my go to for years until they stopped making it. I recently assembled the same Walthers kit using Plastruct's Plastic Weld. No complaints as it did the job.

Dug out a new bottle I had stashed away, and it grabbed perfectly. Thanks again. Posted from Android Date: 09/09/19 22:18 Re: Cement for Walthers Structure Kit? Author: gnguy I second the use of MEK. a quart will last a lifetime and only $6. It bonds real well.
