I am using Durable Resin in a Form3. I purchased the resin in July 2023, and noted how much thicker it is than the clear and white I typically use. Now it seems even thicker and the wiper in the tank really struggles to get through it and often fails. Ot the wiper actually ends up knocking the model off. Thoughts? Is the resin bad at this point? Any tips for using this? I assume theres no way to thin the product at all?
