The issues with these cars are well documented. The adhesive issue makes the above tutorial is a good one and worth the save. Lionel should and my guess will take a hard look at the issue and will hopefully correct it in future runs with an adjusted tape width. It should of never happened and I'm sure they know it. How could they not.
The shell removal while a pain in the butt is a small problem to overcome with folks like Dave sharing his technique. I do like the styrene "wedges" to keep the shell stress down to a minimum. A good solution to a disappointing problem.
