It might just be the model itself. Did you wash it in warm, soapy water first to remove any mold-release residue?

I gave it a wash but maybe not thorough enough? Funny thing is I was so n00b on my first few that I didn't wash them after building, but the Chaos Black is still on there tight. I'm building GW models if that matters.

There are a lot of variable with spray paint - weather, distance, composition of the model, mold releases on the model, factory paint batch issues, etc.

Soak the models in a grease cutter (Simple Green, Super Clean, etc) and scrub them with a toothbrush to remove the bad primer. This should also remove any oils left on the models during the casting process. Do a quick wash and scrub in warm dish-soapy water (I prefer Dawn, since it is specifically made for grease-cutting.) Rinse and let dry overnight. once dry, spray one model and see if you get a repeat of the paint issue - if not, you're golden. If so, you might have a bad batch of paint.

EDIT: FYI, Krylon Flat is great for priming and has the benefit of being easier to toss a can when it goes bad, since you've only paid like $4 for it.

Yep, got the one I did with the paint on primer soaking in Super Clean now, going to try spraying it tonight. Just wanted to make sure this wasn't typical behavior for the Imperial Primer, because the climate I live in is going to make it tough to go out and use the Chaos Black spray in the winter.

Quick question. For zenithal priming/highlighting after you fully prime in black do you use white paint or white primer for the rest of the process?

I use white primer.

It doesn't feel right to kill an unarmed man... but I'll get over it.
I recommend using an enamel-based primer. Takes longer to dry, but it'll hold up a lot better than water-based stuff, and reduces the risk of getting weird swelling/surface texture funkiness. MDF is super thirsty.

Sorry if this has been covered, this is a big thread to dig through.

My first minis I was spraying with Chaos Black, which I know is overpriced but it did seem to work really well. However now it's been hot/humid as gently caress so I stopped by the GW shop on my way home from work and got a pot of the Imperial Primer. It went on fine but I've noticed that it chips off so easily, I can even take it off with a fingernail. The Chaos Black spray on the other hand is on there solid and can't be removed in the same fashion. Is this expected behavior of a paint on vs spray on undercoat or did I gently caress something up?

The potted Imperial Primer isn't actually a primer it's a color match for the black spray primer. Just use Rusto 2X flat black primer (not paint and prime).

SRM posted:

You need to let the MDF "drink" because other wise it will absorb all the water based paint you use. I'd recommend use a real deal primer like Kilz to stop it from absorbing everything. Otherwise you should do a few coats of primer.

Are there any decent two brush blending tutorials that go decently in depth into WHY things work and don't work? I've been trying my hand at it recently, and it's all kinda coming out crap. Either all the paint gets wicked away and I'm left with basically nothing, or there's an outline ringing where the paint was originally, or sometimes nothing happens at all. I realize it's likely that I'm just missing something very stupid and obvious, but I can't seem to figure out what.

If you want to try out fancy technqiues like blending you need to play with additives. Acrylic paint is pretty much only able to layer when used straight out of the pot with water.

Groetgaffel smacked the living shit out of himself doing 297 points of damage.
I just finished my first imperial tank in over a year, and for once I'm actually pretty pleased with the result.
It took me the bulk of two days, in part because for assembly, priming and basecoating I did three at once, but also because I'm a slow painter.

Anyway, pictures. (click for huge)

I tried to add some light soot effect on the end of the gun, and I think it ended up pretty good.
I am however super pleased about how the window turned out.


I painted the barrels in the back red, as if there's any other logical choice for the contents of the trunk of a giant rolling flamethrower.

Any thoughts or glaring issues I should fix/do better for the next ones?

:yeah: There are two things we don't have the luxury of when painting toy dolls: oils (unless you go through the hassle) and special paper material. The closest we can get to oils is if we use blending and retarder fluids and because you're painting on hard plastic with only a primer coating, you won't get the niceties of having paint naturally absorbed by the paper to create blends naturally. And water rings form because of how it dries and what happens if you suck up the water in the middle, either intentionally or accidentally.

The closest we have to what I think you're looking for (a natural, obvious trick), which is the basic key to the blending technique, is the fact that water pools where you left the brush, so you almost always start with learning to pool the water's direction first. Later on you can play with where two colors mix and blend that way.

This may be true of craft paints, but hobby paints have enough stuff stuff in them that just adding water is fine. You can use additives if you like them, but they aren't necessary. I'd like to think I get pretty good blends without them, and better painters than me do stupid stuff.

Paint + water + dish soap at a minimum.

If you live in a high humidity environment you can get away without needing to add retarder since your paint doesn't dry instantly.

The brand of paint also plays a role since all of them behave differently and you can get away with different things when using different brands.

I've found that mixing a cocktail of additives into my diluent mix just makes painting much easier and gives more room for error when it comes to executing blends. No need for this two brush nonsense, I just reload with a second colour and blend directly.

So would adding a flow aid or retarder make it easier to learn blending or 2 brush blending? I mostly just layer now.

IMHO flow aid (or dish soap) is just good practice - it stops your paint from pooling into globs. You have every benefit to gain from using it and virtually no drawbacks.

Retarder will slow the drying of your paint. While I haven't done TBB myself, everything I've read suggests that the second brush is there just to speed things along, so you apply paint with the first brush then blend it in with the second. With retarder I apply paint with one brush, then clean and reload it with a second shade and blend that in directly. Exactly if you were painting on paper. YMMV though as I started off trained on paper so this is more natural for me.

Question about metal primers: I know that leaving black primer visible on a model is lovely and obvious but is it the same for metal primers? Got a dickload of Iron Warriors I gotta paint and I'd rather prime in metallic unless it looks lovely.

I painted up some WarMachine Precursor Knights and Sword Knights for a friend right before a tournament using the Army Painter silver/chain mail primer, GW black wash and just a base coat on the cloth bits/couple of details and I don't think they look lovely. They look fine for tabletop, just kind of unfinished.

I'd imagine they'd look perfectly with a little highlight on the metals and cloth and some more details picked out.

I need some help :(

My main color for my current army is Vallejo Filthy brown. On white primer, it looks great - an earthy, subdued yellow. But after washing, it lives up to its name. I've tried three different washes so far - Army Painter Soft Tone, GW Seraphim Sepia, and GW Reikland Fleshshade (pictured). The Fleshshade is actually the one that works best, but it still takes the color down too much for me. On the other hand, washing is such a simple way of defining shadows that I don't want to forgo the step. Can you recommend a wash? Or a technique that I should use? So far I don't dillute my washes, maybe that would help?

Also. please ignore the highlights on the example mini, I was trying a new highlight color and it's too bright.
