IR guns indeed will not provide accurate info when measuring a shiny object.
However, put a piece of tape on the shiny object, and they will read
accurately.  Seems silly, but it works.

Second, IR gun should be used with some caution. They read the emitted
radiation from a surface (which under the conditions that we are talking
about, is proportional to temperature), BUT the IR emissivity of materials
differ. I would not trust an IR gun reading the temperature of a shiny metal
surface (e.g. gas heater vent, bright copper plumbing). On the other hand,
glass, water, and many paints are at or near 100% emissivity.
