Have any of the KR builders out there researched the expected lifespan for the epoxies and plastic materials used to construct a KR?
I know I have experienced breakdown/deterioration/debonding of some of the various commercial plastic, foam, and/or glued items that I have had over the years. One example is a pair of cycling shoes which had a stiff plastic sole and a vinyl/plastic upper that was bonded together with some sort of glue. After about 10 yrs, the glue started turning into a powder and the bond between the sole and the upper failed. I have R/C airplanes that are approaching 20 yrs old that have no signs of glue deterioration (CA and epoxy glues), yet. Some of the epoxies used have seemed to have undergone a transformation as the color of the epoxy has changed over the years. Thanks, Kenny -- Jesus, who do you say He is?!?! John 3:16
