Hey, Chiselhead; welcome!
I love the font! Beautifully created.
My thought on the paint is that because the wood wasn't sealed first, the spray enamel has allowed moisture in from the back and any bond that existed has been broken by hydrostatic pressure. All it takes is a tiny bit of vapour plus the sun on it and bam, blisters.
That used to be a huge problem with exterior oil paint on older homes, especially on the exterior of bathrooms and kitchens; the water vapour (humidity) on the interior exfiltrated to the underside of the basically waterproof paint on the outside wall and like evil magic, blisters. With the introduction of interior vapour barrier, and breathable coatings, the problem has almost disappeared.
The sign guys here will likely give you more practical advice on how to avoid this issue. Maybe black ink? The gloss will come from your top coating anyway.
Again, great artwork!
