A legitimate point O/P offering here!

Predicate. Speaking here of the label from hell. I’ve experienced a few! Those that defy ordinary “pesky” category drudgery removal procedures. Well toward hazarding potential damage to underlying surfaces.
Observations:
1. Ultra difficult labels to remove, likely manufacturer packaging “defect”. Moreover foreseeable and consequential damage… Manufacturer, “label liable”.
2. Consumers shouldn’t be expected to posses tools, time or expertise to undertake special removal techniques! That particularly where hazarding product damage as biproduct.
3. Pointedly informing the manufacture via product return for adjustment is likely the best way both to achieve best results AND ‘bell over head’ packaging problem notification in graphic format!

4. The aside, suggestion a "gun builder" should be label removal nuances versed… Great point… in 1940 as yet the era of ‘generalists”! “Specialist” nowadays, implying rather the opposite! No expectation in respect of exceptional adhesion circumstances.

I congratulate the O/P for his actions in returning for adjustment with potential notification in wider customer service sense.

My take!
Best & Stay Safe!
