greetings Fragglerock,
If I may, can we take a couple steps back ---
to reconsider:

My dye was at room temp and dyed the piece fine.
Does this particular color of blue have instructions different from Caswell's
other colors they sell? Because the dye should not be at room temp.
You should have it set b/t 130-140dg F.

I then sealed in CASWELL sealer that was boiling.
Again, following a Caswell product instruction set-- this should not be
at boiling temp but instead at 90dg F.

that was anodized at 6amps for 120 minutes at 14 volts.
I am very curious here-- You wrote "6 amps", but did you actually set your
CC at 3 amps as the 720 rule calculated? Following in line with the dissolution
suggestions proposed would point to an actual CC of 6 and not 3. But this
of course begs the next question; What size is your CC power supply? If
its the 3 amp model, ummmmmm. But if you own the 20amp model . . . .

Finally, I will add most diamond plate is of the polished kind from the manufacturer. But this is a very inferior Aluminum alloy when compared to
the traditional "aircraft" grades (6061-t6, 7075-t6, 2024-t3). You may find
a barrel of experimentation to bring this substrate to the likes of the 3
higher quality grades mentioned above.
Also I would not mix your diamond plate with any other grades.
