The stove industry has really migrated through multiple paint suppliers in past 8 years. The leading company had serious QC problems and would not take ownership. That same company's paint was known to produce very heavy off-gassing during initial fires. Most stove manufacturers sourced new suppliers.
Speaking for our company, we went to a new provider, had order fulfillment issues (to be expected when multiple new stove mfg's line up for their product). Great product, hard to obtain.
We are now using a paint that has nearly zero off-gassing, much more uniform adhesion and color after firing. These guys have their act together and have begun to supply many other stove mfg's their paint.
Burn off outside was at one point in time...a must! Now, not so much.
We know who the old company was... who is the new one, and do they sell their product to consumers by the spray can? Is their black a good match to the old company's black?
I did a small (<1 sf) touchup followed by a light blending coat across the whole stovetop last year. It made the stove look new, but I did need to open windows. It was pretty strong.
