Looking at that other thread on weapon quality gave me an idea. And another fun way to deprive rich acolytes of their cash.

Weapon Finishes

Cost : 4g per kilo of the weapon
Weight : 0
Availability : Common
In addition to any other upgrades the weapon has and it's overall build quality it can have a weapon finish. The weapons finish is a purely cosmetic upgrade that consists of coats of paint, laquering, and replacing some weapon fitings with other parts.
A basic quality finish would change the weapon to be up to 3 non-metalic colours divided by parts or simple patterns. This includes basic wood finishes and simple 1 colour designs such as shapes or letters.
Some examples include:

• A lasgun in Cadian pattern camoflage.
• An autogun with a wooden stock and grip with blue casing.
• A black pomeled knife with red blade.
• A stub revolver with pink body and white grip.

Poor Quality
The weapons finish is poorly executed or otherwise inferior quality. It cannot include wooden sections (unless wood is abundant of that world), designs or patterns but different parts of the weapon can be different colours (albeit badly applied and going over the edges). The paint jobs is already going to be peeling or faded.

Good quality
The finish can include metalic sections (but not precious metals), rare woods, semi precious meterials (jade, ivory, bone, moth of pearl), fairly intricate designs in embosed or enscribed work and even small designs or accents of precious metals.
Examples:

• A hellgun with gloss black body with gold etched letters spelling the owners name.
• A hand cannon with a chrome body and with mother of pearl grip inlaid with an Arbites symbol.
• A longsword with a blue metal blade and with a mahogany hilt.

Best quality
The entire weapon can plated in precious metals, inscriptions and designs are fine art quality and can even include a number of small precious stones can be set into the weapon.

• A gold boltgun enscribed with the a saints visage on the side which has saphire eyes.
• A silver rapier sword with prayers inscribed in gold down it's length.

Cosmetic only?
Well that's up to the GM. In some circumstances (such as a ball in a Noble Spire) an unfinished weapon might stand out, giving bonuses to people looking for interlopers that see it. In other cases (such as the underhive) walking around with a pimped out weapon can make a character more memorable, this may be part of idea of course and a character with Unremarkable and blinging weapon is likely to only be remembered for their gun.

cute idea. We have already set up a table for all of it and your idea wuild qualify under the Work of art header as mentioned in the following tables for weapons modifications. And no i did not set up the entire table by myself..as you will know if youve read the other article posted on it...This is the current table ive set up for everything based on a compilation of our two works

Good Craftsmanship
Weapons, Armour, and Items of Good Craftsmanship tend
to have distinctive branding names called their Pattern.
The Pattern Name is usually derived from either where
the item is manufactured (Mars, Lathe, Armageddon), the
manufacturer (Hax-Orthotic, Sollex, Belosco), or named
after the one who discovered the STC or successfully
petitioned the Temples of Mars to sanction alterations
to an already consecrated pattern.

*Items: boost their characteristic bonus' by +5 or some
other minor boost in performance and reliability. Not all
items will need to follow the naming conventions
*Weapons: chose one new trait from the Upgrade Traits List.
Likewise, one Downgrade can be selected from the Downgrade
Traits in exchange for an additional Upgrade Trait.
*Armour: increases it's AP by one for the first hit taken each
round.
*Servants and Services: reliable and will make all service
related tests against a characteristic of 40 higher.

Best Quality
Best Quality items, Armour, and Weapons not only follow the
naming convention of the Good Quality versions but they must
also receive a Unique Name which they had been given at some
point in time during their long and luminous service. The
player must also create it's back-story explaining what makes
it such a magnificent item.

*Items: boost their characteristic bonus' by +10 or,
generally see a marked over-all improvement in performance.
*Armour: only weigh half as much as it normally should and
it's AP would be permanently raised by 1.
*Weapons: have two new traits chosen from the Upgrade Traits
List and can add additional trait from the Downgrade Trait
List for an additional Upgrade Trait.
*Servants and Services: the best money can buy and will make
all Characteristic Tests in performance of their duties
against a characteristic of 50

Now obviously there are some simple rules with this to avoid confusion.

(1) you CANNOT take opposites ( I.E. taking deadly AND low damage ) since these would cancel eachother out and be a waste of time

(2) NO you cant take more than 3 TOTAL modifications/upgrades for a BQ weapon. The limits are worded precicely for a reason ( 2 upgrades OR 3 upgrades AND 1 downgrade ) so NO going hogwild with them

(3) EACH upgrade you take will increase both the cost AND difficulty of making/modifying or finding someone who can do so for the weapon in question

(4) For simplicity sake when modifying an existing weapon you are granted ( free of charge) the weapons base traits ( such as accurate for a long las) that do NOT count towards the total modifications you want to make...these listed with the weapon are a part of its basic design ( unless you wanted to remove them for some ungodly reason...lol )

(5) You will have noticed that i have the traits divided up between those that are for melee and ballistic type weapons to prevent confusion as to someone otherwise inevitably putting a upgrade on a weapon type that is isnt made for ( i actualy had a player try it before i modified the tables )

Anyway here is the setup for modifications that my group and i are currently using i hope you like and feel free to use or modify as you see fit

Yeah, i was reading that post and that's what got me thinking. When I saw the work of art entry I thought, seeing as it was changing the whole weapon, that you could change the entire design, making a chain sword look like lizards jaw, see though guns, power fists like deamon claws etc.

I thought it would be a bit of fun for people who can't afford to get the good or best quality version of the weapon (or if they get hold of a weapon that's already good quality) and just want to personalise it a bit (or gold plate it).

I've probably been playing Army of Two too much but i think this is the place for it.

Thinking about it, I can't see any reason these rules couldn't be applied to armour as well as weapons.

DIY Weapon or Armour Finish Application.

Cost : The basic cost of materials and additional assistance is 75% of the normal finish cost.
Time : The time taken is an hour per kg of the weapon (this is multiplied by the quality cost multiplier).
Roll : The basic level upgrade is a Trade (armourer) or Trade (weaponsmith) (+10) roll. If the roll is failed by less than 20 the weapon ends up with a poor quality upgrade. If it fails by 20 or more then the upgrade is not successful but in both cases the cost is still expended.
For good quality weapon the roll is challenging (0) and for best quality the roll is at -10. In effect trying to make only poor quality finish is a +30 test in total (though any failure fails to apply the finish to the weapon, although this is the same chance of making a poor quality finish as the normal quality test the time and materials cost are reduced and hence the final effect is limited to poor quality at best.
For every extra degree of success the craftsman can reduce the time taken by 10 percent (minimum of 50%) OR reduce the cost by 10% minimum of 25% of the base cost.

Assistance : Anyone with the same skill can assist the craftsman as normal.

Other skills:
The GM may decide that other Trades are wholly or partially applicable depending on the desired finish and can therefore assist in the creation. Examples include.
Trade (scrimshaw) – Engravings or reliefs
Trade (art) – Painted pictures, illustrations or designs
Trade (copyist) – Illuminated letters or script

Oh here's some blingspiration for your guns too.

Another good chart to take inspiration from, especially for weapons of Chaos, or warp altered weapons is the Chaos Armory in the Tome of Corruption.

Will repost some of my favorites today.
