So I titled this describing Mod Pod as a hobby rules-breaking product, because for me it is.
It's not a new innovation to use Mod Podge as a mini. varnish by any means. I've seen TMP members post that they've used it as a mini. varnish.
I began to use it on plastic terrain board a few months ago but was hesitant to use it on minis. because of how thick it is. It's designed of course to be a puzzle/picture/craft project sealer and it does dry entirely transparent.
So I finally tried it on some metal dwarves that I painted a couple days ago. Once again, Mod Podge delivers! And with some amazing side benefits!
You seriously do not need to every bother with hobby varnishes in terms of being the primary protective layer for minis. Why? Because Mod Podge delivers a coating that is FAR, far thicker than even gloss brush-on varnish. Not even close. It gives the minis. a thick, slick, resistant surface. The matte however does have some sheen to it so you may need to put a single coat of matte varnish over it to dull it. But not a big deal.
If you haven't ever used Mod Podge, you need it. It will become your best hobby friend.
Another benefit of Mod Podge is that it breaks the rules of priming. What I mean is, whether you are painting plastics or metals a solid primer coat is NO LONGER AN ESSENTIAL. Yes, it's always helpful of course, but not the actual thing that truly secures your paint. If you use a weak primer, or a spray paint as a primer, or a good, true primer for your mini. Mod Podge secures it from above beyond what any varnish could.
I've got a friend who actually uses no primer on plastics and puts Mod Podge over the paint jobs. They wear like iron, tough as nails.
I know there's going to be some primer purists here on TMP who say I'm full of it (I won't mention any names), but I'm telling you that Mod Podge offers a freedom of protection where it's ok if the bond between the paint and primer underneath isn't perfect or even strong. Mod Podge traps the paint job in what amounts to a thin, plastic-like shroud. It can't move even if it wanted to lift off the primer.
My point to this is that Mod Podge also allows you to do things like for example if you miss a mold line (which I don't know how I manage it but I find a way) after you've started painting, you CAN go back and scrape the paint off right down to bare metal or plastic and forget primer for the touch up area, just touch up the areas with paint directly. Mod Podge will secure it. Or if an area where primer misses. You don't have to touch it up with primer. Just paint your colors and you're good to go.
Seriously. Now of course you do still generally want to give your models a primer coat, be it spray or brush on. It's certainly always better to have both a good bond underneath and a solid protection above. But with Mod Podge you don't have to worry about touch up areas if you don't use a "pure primer" on your models.
*By the way – I've noticed that even SELF-ETCHING primers can be scraped off metals without a great deal of force, it's not a super strong bond. I can scrape primers off plastics without much force, be they spray or brush-on. No matter what you do, the bond between primer and model surface is not going to be impervious to chipping and wearing. I've tried a lot of true primers as well, hobby and otherwise. None of them are that resistant to being rubbed off, certainly not totally resistant if a model is dropped.
If there's some secret miracle primer out there for models that only a few select insiders have access to, I'd love to know what that primer is. Because that's the way some TMPer's talk about it. Like NO hobby primers are true primers. Well then what on earth IS a true primer? People talk about it but never seem to say what that product actually is.
It's the REVERSE. What you put OVER your paint job is what is going to secure it when you being handling and gaming with it.
Now I know there will be responses saying that "if you prime properly you don't need any varnishes, it's the mark of a bad primer if you have to varnish at all."
Sorry, but that makes no sense. At all. I have yet to see any primer out there that can resist handling or dropping without paint coming off. A paint job with primer and no varnish, you better get ready to a lot of touching up if you game with them.
I'm sorry but that's rubbish. Pure rubbish. I proved it with my own hands-on experiment.
Pics. of metal dwarves. You can see that the Mod Podge dries perfectly clear and even used at full-strength thickness leaves no clumps or globs. Model detail and colors are perfectly crisp. As long as you're careful to use a very thin coat as you're painting it over the model and take care to not let it collect in recesses, they come out with a perfect protective coat.
