On larger scales I’d go for small applications of gloss acrylic gel, a white goo that dries transparent.
Dripping slime can be done by first attaching (with acrylic gell) a short (or long) stretch of clear stretched sprue, or any other transparent fibrous material, letting that dry, then applying more acrylic gel to form a slimy drip.
Tears on smaller scale I’d use gloss varnish, slightly thinned perhaps.
See pics for some examples.
Hope this helps.
