Anybody here have problems with Rustoleum American Accents 2x Ultra refusing to cure on plastic? I cleaned and degreased a few new, stock, glossy plastic knobs and lightly scuffed, cleaned, and degreased two new Jazzmaster pickup covers, allowed them to sit overnight at room temp, then did my normal spray routine: a light coat of warmed rattlecan color followed by three more very light passes every 15-20 minutes. Their initial dry-to-touch process took took hours in my basement "clean tent" where it's vented & low humidity but then I moved them upstairs to cure for 12 days where it's about 68 deg F and slightly more humid (but not humidified, our house is relatively dry in the winter).
When I shot them with the first light pass of clear tonight the knobs were totally fine but as soon as the spray hit the pickup covers the paint layer bubbled up. I admit to not giving them a fingernail test beforehand but the paint felt hard as a rock and I had no reason to doubt these were still in the danger zone -- if anything I could understand the paint refusing to adhere to the glossy knobs.
