Dear all,

I am back after long hiatus in model AFV making..well I was trying to putty up the Tamiya Dinosaurs for my kid.

Why doesn't the tamiya light curing putty harden after 1 hr? I left the kit under the lights of my living room. Its still sticky to touch. Its a thin layer like grease between the leg joints

It aint cheap but cant work (like the 2 part resin putty)...

Help

I have never used this or even heard of it actually but the web site says that it will not cure under normal room lights. Seems it wants sunlight or fluorescent light. I would say try taking the stuff outside for a few mins and see what happens. Here is the web site I am talking about:

Normal incandescence lights do not have UV rays, put under sunlight and you will see it curing in about half minute...

a note to bare in mind is that once it dries it is left with a thin sticky layer on top, I always just wipe this off and sand after that.
never had any other issues with using it though.

I use the Light Curing Putty as well, but set it under a halogen downlight or bathroom heat light. Only takes half a minute. Just be careful not to melt your model if you hold it too close or for too long! It wont set with fluoro lights.

Is this similar to Squadron Green, or White, putty? One minute seems like too short a working time. At the other extreme, I prefer Tamiya's two-part epoxy putty. It has a very long working time, and can be rolled very thin to make flags, bed/tent rolls, tarps, and even items of clothing.

thanks guys. I tried curing under white lamp, it cured.
