Oven cure makes no difference unless you're talking about powder coating or the new UV cure paints. The carrier solvents need time to leach out, the oven can speed that up but only at 120 degrees or better. Usually paint shops keep their booths at 80 or so just to stay in the cure reaction window.. and cure catalysts are aggressively reactive to the vinyl adhesive. It's chemistry. Results of reactions can take up to a year to surface.. microscopic bubbles from out gassing make adhesive failures, and catalyst cure reactions in the adhesive layer cross link the resins and harden the adhesive prematurely.. hindering the removability.
3M Tech's can, and do, analyze film failures. They can determine if you applied wet or dry, what prep chemicals were used, and whether the surface was cured. They can even tell if you used rapidtac or soap. Take one of their classes... Ask their rep.. A few days wait isn't unreasonable. Rushing thru it is unprofessional.
