Rain FX R&D (In Progress)

Been trying to familiarize myself with some basic FX in Houdini and Renderman Here is a test of what I got so far trying to create some rain using POP particles for the fx elements and a basic pyro setup for the tire mist all put together in Nuke

Currently I'm struggling to get the wipers to wipe the water tails across the windshield using a POP setup so let me know I should keep trying or give FLIP sim a shot for that.
I also need your inputs to make this better so feel free to drop in suggestions and tips!
