I haven't heard that before.
The older caps were "batter dipped" and the coating isn't always uniform in thickness. I've seen or used some with air bubbles, knots and runs/drips in the finish. Whereas, the modern caps have a coating finish that's very smooth and uniform.

I have those caps in my Music Man and when I put them in(replace w/ current production 6PS) I didn't notice any firecrackers go off other than they were a bit smoother... Great Score and Good Luck on the build!!

Tom. TM basically said it. The old ones are quite non-uniform, sometimes on the larger ones the bottom in between the leads have no dip on them! Others were over-dipped and the excess sets up in ridges.
The new ones are somehow covered in powdered epoxy or whatever it is, then baked. It appears to be a thinner more uniformly applied layer and when baked it melts but doesn't run.
Tony, Some info from Mark Huffman on the difilm vs 100% polyester:-
"The later OD have brighter orange color (usually, sometimes the older ones can be bright, but usually dull orange) and can either be 100% or difilm.
It appears that there is a way to tell without testing.
Speaking of later generation bright orange: The difilm all (thus far) appear to have three lines of writing on the cap. The 100% polyester appear to all have 2 lines of writing.
You can also test the value. The difilm of the same era as the early 100% are 8 - 20% over nominal and the 100% are near nominal. This indicates that there is a chemical change in the difilm.
I am going to go through more caps and see if there is in fact a way to tell difilm from 100% by the text on the cap".
