Lordy Lordy... again, thanks for the advice on other glues. But my point seems to be getting lost somewhere along the line. Revell Contacta worked fine on the first several Rubicon kits I made. Behaved as it was supposed to. But is not behaving the same on the CMP truck kit. Meaning either the plastic has changed, or something has changed in the glue (or I’m going potty!)
No, your note was not lost somewhere along the line, but maybe my note about first testing the cements/glues on new plastics before starting a project was lost somewhere along the line. To be honest, I'm surprised you had good success with the Revell cement because I found it doesn't have what it takes compared to other cements. Yes, you can still use the Revell cement to build a Rubicon, but why when there are several other cements available which work so much better?
Also, Rubicon is now using a medium gray plastic instead of the dark green. The CMP truck kit is made of the newer gray plastic. However, Rubicon says its the same type and quality of plastic as the earlier dark green, but if you are having a different results, then maybe its not 100% the same. It seems obvious - and why I did not really stress this in the first place - but why not look at using a different cement? Have you tried using the cement Rubicon recommends?
Maybe its not common knowledge, so I better mention that not all plastic model kits are made of the same type and quality of plastic. The type of cement you use to assemble a plastic kit can make a big difference.
I hope this helps, and happy model building.
