Hello! In my university, we use Smoothex Debubblizer by WhipMix. It's a spray that breaks surface tension between the wax and the model, allows the wax to run smoother, and prevents the wax from sticking to the model.
Who wants to look at a ground down tooth with just wear facets. But yeah. The metal finisher would grind the shit out of that and then the boss would get pissed cause you wasted aoo much a90😂
