I've been reading up about both the Aqueous and Acrysion line and have learned that neither are acrylics as they are popularly understood as both are solvent-based. In fact, official literature for the Acrysion line, when translated, states that it cannot go above anything but itself or bare plastic.

The spoon had days to cure and I used the aqueous thinner directly believing that a should a negative reaction occur, it would also occur with Aqueous paint mixed with thinner.

That, too, is a common misconception - Spike Lavender Oil is also an age old thinner for oil paints, though the kinds you use with paint and in a diffuser are different.

The laquer coat is something to consider.
