First of all I'm perfectly aware that there are few mods that do the similar thing. However I wasn't 100% satified with what they do and how they are written. Thus I've made my own mod for the personal use. As ususal I'm sharing it, for maybe someone else will find it uselfull as well. If you are 100% good with any similar mod, then just keep using it and refrain yourself from making any retarded comments here please. Now to the point.

Compatibility patch for Impervious Power Armour added.
Because there was literally no sense in adding one more ESP to your load order, I simply re-wrote ESP part of the mentioned mod. So overwrite Impervious Power Armour.esp when asked. You still need the original mod!

Added integrated support for US Army Paint, which means no additional plugins needed. If you don't want these paint jobs, just don't install US Army Paint. It's not a hard dependency.
How to make it work if you do.

• Download and install PAPJ.
• Download and install these files from US Army Paint mod. "US Army and DotA Pack", "US Marines Standalone Pack", "Winterized Pack" to get respectible paint jobs covered for all supported armor types.
• Disable or delete all esp installed by US Army Paint mod, as you not gonna need them.
• Enjoy.
  

Upcoming: Full support for raider PA with integrated Raider Power Armor Chop-Shop support.

I had two simple goals in mind while making this. To divide material mods into paint job and plating and to make a more logical bonuses for the paint jobs.
This way there should be minimal to no impact on the game balance. In the process I've made a few other alterations. Let's get to the details.

What it does exactly:

• All material mods that don't have any impact on PA appearance are now considered as armor plating and installed in a new plating slot.
• All material mods that do change PA appearance are now considered to be a paint job and installed in the same slot as before for compatibility with paint mods.
• Paint will no longer give any physical bonuses, like strength or resistance. It will give mental bonuses instead. Luck, Charisma and etc.
• Plating (material in vanilla) and Misc mods will no longer change PA parts name. Always hated those redicilously long and inconsistent names.
• All paint will no longer require any material for construction. All other construction requirements left intact.
  

Paint jobs bonuses:

Atom Cats - Luck +2
All BoS paints - Perception +1
All Hot Rod paints - Charisma +1
Railroad paint - Perception +1
Minuteman paint - Charisma +1
Institute paint - Intelligence +1
Military paint - Perception +1
Vault-Tec paint - Charisma +1
Winterized paint - Perception +1

Power armor covered by this mod: T45, T51, T60, X01, Tesla T60, Vim T51.

To get a picture of how it looks in game please check screenshots.

All requirements can be checked in the requirements section of the page. It's a standard section on any mod page on this resource. If you never heard about it, familiarize yourself with a mods page structure. I don't feel like writing requirements lists for every mod while there is an intergrated feature for this.

Compatibility
All current and any possible future DLC paints are compatible without patch. All standalone paints should be compatible without patch on a condition they don't alter instance naming rules. If they do, just load this mod last.
Any mod that does a similar alterations is obviuosly fully incompatible and will never be.
Any mod altering any material modification for PA is incompatible.
I also strongly discourage you from using AWKCR as it adds mess to all PA parts. While technically compatible it does things, that framework shouldn't do.

Since you are interested in PA, you may also want to check my other PA mods.

Power Armor HoloHUD - to replace vanilla PA HUD with much nicer holographic HUD.
Power Armor Re-Frame - eliminates frames clipping and allows you to see your BoS underwear in PA.
