Testor's contour putty

I have a partially used tube of this product, and a brand new tube. When I squeeze either one, all I get is a clear amber fluid. I tried applying it and letting it set up. I dries to a clear convex surface that isn’t completely dry after 24 hours. Is this what I should expect from this product? I even tried “massaging” the new tube to mix the contents and got the same results. I was expecting some sort of white product like Squadron White.

I have no idea WHAT I used the partially open tube on; it has been so long, I’ve forgotten. I normally use Squadron White, but it shrinks and cracks. I have to reapply to get a firm surface. I’d like to try something else; thus the Testor’s question.

I’ve used it a lot and I usually have to squeeze out about a dime size “blob” and mix it as there will be liquid and solid intermittently coming out of the tube. Kneading/squeezing doesn’t seem to help for some reason. It works really good on plastic kits but primer it before painting.

I’ve used it once, fresh from the tube on a rather complicated model project, and it worked very well. However, I’m wondering if it isn’t a lot like good old standard Wood Putty, where once used, the remainder never seems to quite jell back to what it was to begin with. I do remember that the initial application went smoothly, but several days later, when I had to put on a second application before sanding, I had to knead the tube quite a bit to get a proper mixture. Which makes me think that air contact with the material in the tube tends to degrade it over time and make it fairly useless. Like wood putty.

Just a thought.
