Number removal

[Gregory_Schulz@mil-elect-tool.com]

The nos. and stripes appear to be a super thin mylar.
The adhesive won't soften with a 1200 watt hair dryer.
Trying to peel this stuff off ends up in a futile excercise
of chipping teeny little bits off, one at a time, for ever.

Does anybody know if there's a type of solvent available
that would soften or lift the numbers without destroying the
42-year buildup of paint?

Thanks in advance,
G.
