Tap Plastic's EX-74 is a two-part expo resin finish I have used on my DeLIVEry series. It's relatively easy to use but a bit pricey. The user does not need to be a chemist, but to be successful, one does require to be prepared with proper equipment and dedicated time. The product is only available in the US and needs to be delivered by ground. The couple times I have ordered it I was hit with a hefty customs charge. On the positive side, the product covers a lot of surface. Good bang for the pricey buck. The final finish is very glossy, like glass. The reflective quality of the epoxy provides a depth to the collaged layers which makes visible the hidden gems within my paintings and lets the colours sing. I appreciate how the epoxy seals in all the textural elements of my work. The distressed and torn edges within each piece appear precious. Tap Plastics has efficient and helpful on-line customer service. I have emailed many user-related questions and heard back each
