Typical Noob question here for the hive-mind.

I used brush-on primer for my Blackstone Fortress models. Vallejo's model black brush-on primer worked a charm, but Army Painter's grey brush-on primer is flaking off my negavolt cultists like nobody's business. A gentle rub with a finger nail will cause it to scratch off/chip.

My question is, should I just go ahead and paint them, followed by some brush-on Army Painter anti-shine matt varnish? Will that be enough to keep all the paint on there? Or should I re-prime? (The weather's improved here so I can spray prime over the top of the first coat with Army Painter white - but I worry it'll cover the detail of the models, especially since the coat of grey primer already seems quite thick). Any tips much appreciated.

Would also be interested to hear people's general thoughts on brush-on primers and varnishes, techniques, brands, etc.

I'd recommend stripping the models that you applied the shoddy primer to and then repriming. You may get an uneven finish if you paint/prime straight over the old primer coat.

I didn't think Army Painter made brush-on primer, so you may be using normal paint - just a heads up.

Thanks for the response! Might be tricky - I'm a foreigner in a strange land and not sure how to go about stripping paint or where to get supplies. And anything I've got left in a couple months gets tossed, so I'd prefer not to be buying too much else. If I can't sort stripping the paint, any thoughts on which route is best? I mean, the current primer looks fairly smooth and even (though definitely rougher to the touch than the Vallejo), just flakes off easy. And so far I've protected them well enough that it's only the bases that have the scratches...

Here's the one: https://www.leodisgames.com/shop/hobby/army-painter/brush-on-primer/ [or just search army painter brush-on primer if links get blocked here]. But yeah I hadn't really seen it anywhere apart from the store here in Russia, and nobody seems to be mentioning it online really! Maybe this is why!

Thanks for the response.

Any store that sells camping gear should have liquid for campign oven. I use that to strip models to plastic, resin and metal models.

Isopropyl alcohol or rubbing alcohol works wonders. Get a bottle that is 90% alcohol or better. Throw them in and wait a couple of hours.

that's basically the stuff I mentioned. And I don't even need hours. I have them for like 5 mins and then start rubbing. Albeit maybe waiting couple hours would mean less rubbing...which arms and back could enjoy...so time or effort?-)
