Not really a model specific guide as my template for my Entire DG army. these models are heavy with rust and effects. So be cautious and what order you do so you don't get rust on stuff where it doesn't belong such as tentacles and robes. Just a word of advice

this is a good article for alot of stuff if you want to swap in and out effects and such

Prime the Model (zenithal method)

1. Prime the entire model using any black primer.
2. Allow time to dry. Follow up with a few blast of wraith bone from the top of the model to pick out the lighter areas
3. If you want to go extra one blast of pure white from the very top

Or is model specific. ==========================================================================================================

Tabard (White)

1. Basecoat with celestea grey
2. Wash with agrax earth shade
3. Wash again with Agrax Earthshade this time focus on the bottom of the tabard areas

Boney Protrusions and Spines --- https://brushandboltgun.com/2017/10/15/death-guard-painting-techniques/

If you are painting thos esmaller ones these gets aliitle harder to get details unless your good. I usually stop after step 3. good enough espically after all the effects

1. Base with Rakarth Flesh, then wash with Citadel Seraphim agrax earth shade
2. Reapply Rakarth Flesh, leaving the Seraphim Sepia in the recesses
3. Highlight the ends of the protrusions and highlight with Citadel Ushabti Bone
4. Mix a little White with Ushabti Bone and add final highlights to the raised areas.

Skin Areas

This incluse organ tubes that are popular with deathguard.

1. basecoat with Rakarth Flesh
2. Cover all over with Druchii Violet
3. mix a 1:2 solution of Rakarth Flesh and Druchii Violet :. goal here is to hit the pertruding areas. Hazing a glazed effect
4. Apply Carroburg Crimson to areas touching arrmor, metel are anything else. hitting areas where the tears would be worse
5. I personally like to make the tubes inside of htese tubes looke copper ish. I use Screaming Bell thin hit it with Agrax Earthshade
6. highlight selectivly with Rakarth Flesh
7. above those highlights use Ushabti Bone

U can change some of the tubes with Runelord Brass Balthasar Gold or Screaming Bell Just go with waht you feel is right

Sctythe

1. Hit all the meteel ares like the main sytche head with Leadbelcher . paint the main scythe area of the blade with Black Templar or really thinned Abaddon Black
2. hit the tip fo the sctyhe and up about 1/3 of the way with pure Abaddon Black then grab water and start glacing up the rest of the weapon aming to the power pack at the top of the sctye
3. paint the wooden areas of the scyhe with a basde of Dryad Bark
4. Basecoat straps with Mournfang Brown highlight Gorthor Brown . Dry brush is ok
5. hit the wiring with screaming bell to make a copper tube look
6. Highlight balck areas with Skaenblight Dinge
7. highlight metel with runefang steel

Tenecles (not tubes)

Not 100% happy with this. May try something different

1. Basecoat in Screamer Pink
2. shade with Carroburg Crimson
3. highlight with Screamer Pink
4. smaller highlight with Pink Horror
5. fade out Pink Horror transitioning with Emperor's Children

Leather straps (need to complete this)

1. basecoat brown leather straps Mournfang Brown

Ruptures and green neon highlights

1. base coat areas with a highly watered Trooper White
2. apply Green Fluorescent
3. apply watered down Nurgles Rot to achieve a watery oozy effect

boils

1. basecoat Averland Sunset
2. if there IS skin around boil apply Carroburg Crimson right around boil. followed by a medium or watered down and Carroburg Crimson going out see dunchan roads painting choas cultist for instructions
3. apply Yriel Yellow on the bottom half of boil
4. put a dot of Ushabti Bone right in the middle of boil
