Surface Shaders: Damaged and Dirty Procedural Material Effect or Shader

I have been creepin the store for a while now but haven't found the right purchase for a dirty or damaged procedural material effect. I simply want a shader or effect like the ones listed below but better....hard to explain.

*I know substance can sort of do this but it's been known to have a lot of issues with Unity and so has been blacklisted. *Things like Shader Painting systems are overkill so don't list those.

There is Worn Edges but it's not procedural and heavily outdated:

The oriental image below of before and after is basically the effect I am looking for:

There is Wet Stuff and it works great for adding water damage+it's an effect so no need to use Shader:

Surface Shaders is a very good example but I'm looking for and it gets pretty close:
https://assetstore.unity.com/packages/vfx/shaders/surface-shaders-71664


Lux LWRP Essentials counts too:
https://assetstore.unity.com/packages/vfx/shaders/lux-lwrp-essentials-150355


Does anyone else know of something of a similar nature to get these very nice looking effects?
I have only listed the asset store options and there may be others like from Github feel free to post them here.

 

Update 2: That Zero Gravity is depreciated, I would not recommend it.
Update: I have added this from the Zero Gravity asset pack https://assetstore.unity.com/packages/3d/environments/sci-fi/zero-gravity-part-one-102764



If anyone has used that system please let me know it's looking great so far!
Only problem is Shader Forge has been depreciated.

 

Update I appear to have found the solution, I don't know what do you think?
Distress & Layering Shaders
https://assetstore.unity.com/packages/vfx/shaders/distress-layering-shaders-114164

 

Update I have tried out the Distress and Layering shader and can attest that it's quite amazing, the effects it can do to the mesh are quite amazing. It works best if the mesh has UV's and it's quite excellent the results. Aside from the picture above with the tank and cars the shader has 3 layers and I used it on my Rocks and it was able to mix 1 layer for the base rock and another for the sand on the rock and another for the snow, the effects can all be hard or softened blending it's quite mad! I am a little lazy to provide pictures right now but if needed let me know!

 

Hi, it's been a while since you posted this but I am interested in doing the same thing.
But it seems you have to spend a lot of time making masks for the the rust and scratches yourself?
If I have to spend hours in Photoshop making masks, I might as well create the whole shader/material.
I can't seem to find any documentation, so I must be missing something.
Some tips?
