Generic model release + new asset I painted/made myself.
Guide for getting the most out of it:
Always use the colorcorrect assetbundle with it, it makes the colors way nicer, I always tiny my lights slightly creamy/yellow but you can use white. The metal strips on the back can use reflection probes so load it in an environment that has them and it should look pretty good. The specular textures for the wet spots show off when there are more than 1 lights active and depend where the second light is and your camera angle. I have added a video of them working with a basic point light moving up and down so you can see.
One side is more dirty than the other.
