OK Cato, I have not seen anyone else post this method. Disclaimer: I have only done this once or twice, and that was a LONG time ago. The details are a little foggy. You may find better instructions on some of the military modeling sites as that is where I read it. As I remember, you heat one end of the sprue until it actually runs. (I think I actually caught mine on fire. I'm not talking forest fire here, more like an incense stick or match stick fire. If it does catch on fire blow it out). Anywhoooo, you basically stick the melted end to your workbench and pull. I was able to get hair fine strands every time. Once the sprue cools it pops right off the bench. I hope I explained this well enough. If you can handle a match stick flame, you can handle the sprue flame. I personally had more control with this method than I have with the holding the sprue over a flame method.
Yes, I have heard/read about it but I have never, that I can remember, had a poor outcome because I shook the can. I think the possibility of a poor outcome from not shaking the can enough would be greater than the possibility of a poor outcome from shaking it.
Hi Mark. If your response was to my picture, thank you. The picture is over-exposed. I'm sitting here looking at the model and the red portion of the decals is a darker red. The blue is also darker than what shows in the picture.
I just run hot tap water into an old water pitcher. The cylindrical, tall, old fashioned one. I put the can of paint into the pitcher and leave it in there for a few minutes. I take the can out, shake the heck out of it, while at the same time running more hot water back into the pitcher. I do this two or three times until I feel the can of paint is uniformly warm.
