|Modelling / Construction|
|The Construction forum is for the discussion of techniques on the construction phase of AFV modelling and the tools and materials used.||
I was cleaning up my shop this evening and picked up a pair of DS tracks I had sitting off to the side for an ongoing Brummbar project. The tracks had already been glued together, painted and wash-weathered about a year-and-a-half ago.
To my utter surprise one of the tracks felt stiff when I picked it up and pretty much snapped like a potato chip in my hand!!!
Upon closer examination, it appears to be shiny, as if something was leeching out of it, although it's dry to the touch. The other track is only partially in this condition, with a good length still flexible with a flat finish. It, too, snapped very easily in the shiny area.
From what I recall, I glued these tracks with Tenax and brushed a little Tenax on the edges to remove mild parting flash. The tracks were base-coated with Testors Model master acrylic paint via an airbrush. Weathering washes of Testors Model Master acrylics, enamels, and oils thinned with odorless terpenoid were applied with a regular brush. Both tracks dried to a nice flat/semi-flat finish a few days after these washes and were awaiting more weathering.
This was a total surprise to me. I can't imagine what would be going on right now had these tracks actually been on the model. Kind of reminds me of issues discovered with other "flexible" plastics - like those rubber tires in a/c kits that would melt the styrene they were in contact with over time.
My camera battery is recharging right now. I'll take a photo tomorrow and post it. Has anyone else heard of issues with the DS plastic?
