Clear graduations enable accurate mixing ratios for common paint systems, and the transparent cup lets you easily see liquid levels at a glance. Suitable for mixing resins and paints across fiberglass resins, automotive coatings and varnishes, as well as stain, sealants, gel coats, varnishes, and polyurethanes. Easily refilled, and compatible spare cups can the cup at any time, reducing cleaning time and the use of cleaning agents. The cup and lid connect by a screw joint, so the cup remains attached to the lid and spray gun even when bumped by obstacles. The lid can be removed quickly in emergencies without soiling the working area. Use scenarios Automotive refinishing: use to mix base coats and clear coats with precise ratios. The graduations aid accuracy, and the screwconnected cup stays with the lid during movement, while spare cups enable rapid color or batch changes with minimal downtime and cleaning. Fiberglass resin work: mix resin and hardener to exact proportions. The transparent cup helps monitor levels during multistep resin systems, and the secure screw connection prevents accidental spills if the setup is bumped. Keep a spare cup ready for a batch. Wood finishing and coatings: mix stains and polyurethanes or varnishes in controlled ratios for consistent results. Readability of liquid levels reduces measurement errors, and the removable lid allows quick cleanup in case of a spill or emergency without contaminating the workspace.
