Howdy Timmah,
Yeah, burning thru it happens. but when you do get it right, the results are a nice tight "guy wire" that can be painted and wont "sag".
Some other little trick I use for other details are: Using the wire out of a bread "tie twist" for antenna, on both aircraft and armor models. By stripping off the paper or plastic coating, you can easily fashion a "whip" antenna for a tank by wrapping part of the wire around a needle (see photos in my gallery) or make pitot tubes and antenna for aircraft.
Also using a drop of clear fingernail polish over the gauges in the cockpit and on running and navigation lights (it makes the guages look like they have glass over them and really brings out the nav lights).
I also have a photo of how to make a "canvas" for a cargo truck in my gallery using a piece of nylon hosiery (panty-hose).
Anyway, if you want to look at my gallery, click on the link to the left of this post under my name.
Glad I could help you out, have a good day,
