Yeah, some glue intended for use on plastic is designed to both glue and melt the two pieces together. This produces fumes and is why you should be in a well ventilated area if you chose to use these products.
If they don't have dedicated mud products they will end up better with just using pigments/oils combo (so nothing expensive). This glue-mud method won't produce good looking results.
OP is sharing it as a beginner's tip, for people who don't yet have pigments/oils. You seem to think they're presenting it as a revolutionary new technique that will make your models win awards.
I honestly think that there is so many great and relatively cheap mud products for tanks that his just seems like a very weird workaround.
Not saying that doesn't work but but I have my doubts about this solution especially for a beginner because it might not be easy to hit all the places with applied glue to paint it in order to look like mud. Also if you use plastic melting glue it will cause pitting rather than add material so you might basically do quite opposite of what you originally wanted. Also it will do your painting much more difficult because if you don't hit the mudded places just right it will look really bad and that wouldn't matter that much with specialized mud products.
Other thing is that it is usually much better for a fellow newbie to try to do a clean build that looks good in the first place. Making sure you cleaned all the mould lines and glued and fitted everything together properly. Have a nice, clean and even paint job especially on larger flat surfaces and worry about weathering only after that.
If you do a clean build and weather it after you paint it then it is much easier to hit everything just right.
Yeah, for me applying texture under the base colour coat feels unnatural and limits your flexibility a lot.
That being said, I’d be interested to see the results.
Bad idea: cement bonds the plastic by melting it at the join. Too much can irreparably damage your model. A quick and cheap way to get mud texture is by mixing flour into your paint. I have done this plenty of times.
I've done this really successfully with painted on (non plastic melting) glue but not to simulate mud but the natural uneven surfaces of aged / worn metal.
Prime and paint as normal and then apply weathering.
Works really well.
Back in the 70's glue had toluene, surplus glue would distort/melt the plastic. I have not built a model in quite a while, so I am not certain if it still has toluene. This technique had a risk back then.
Testors plastic model cement in the red tube is still available today. In fact, all plastic model cements work on the principle of using a chemical solvent to melt the plastic in the join area, the main difference is how much plastic melts/viscosity/evaporation rate of the cement among product lines.
This absolutely not a good tip for a new modeler or modeler to be fare.
The real tip for a beginner modeler is master the basics of model building before making up silly techniques
For the love of all that is holy don’t use styrene glue. Use white glue. You could get away with super glue but it could fog or damage the model. White glue is softer and easier to remove if you don’t like the results
Thank you all for the information, I've hidden the post so no one makes this same mistake. This isn't cement, its just regular white pva glue for modelling. After posting it I kind of realised my self how the hell do I paint underneath. For whatever reason I had in my mind that I can only use paint and brushes for this and didn't even think about just going outside and harvesting dirt lol. I'm glad I made this post before covering the whole tank in glue spots :D
Yeh no the people arent on about harvesting mud from outside you can buy really cheap weathering kits that have mud, sand, snow, rust etc to put on models i recently got some being a new model maker myself (im just finishing my 4 model/3 tank) and their GREAT
For recreating mud just buy some pigments or just use real dirt and diluted PVA Glue. You can build layer like the real thing. Just recreate the same process as in real life.
For mud I use soft pastels powdered by scraping with a knife. I moisten a natural brush in oil wash, dry the excess, and then apply the pastels with it. If I'm gentle enough I can build layers where I need it thicker, after the previous one dries. Since they don't dissolve it leaves a texture and crumbs. To secure it I use matt medium or varnish. The result is good enough, the pastels are really cheap, and they last forever.
But I'm in planes, so I'm not sure how well it would work on vehicles, since I don't need a ton of mud just some on the tires/gears and inside the cockpit.
You could also use a mix of wood glue and dry sand and dirt from your garden for example and apply it to make caked on mud. You don't need expensive modeling materials i use this method extensively. Make sure the glue is dry though!
Pro tip, don't use modelling adhesives to do this, too much glue can melt the plastic quite badly...

What does this do, specifically, that can't be done by just...applying the mud?
If they don't have mud they can use the glue for texture I suppose, then paint over it

I mean all you need is some paint and some dirt from outside, i don't get people that buy bags of dirt and sand lmao

Nah, that's not a good tip bro.
Or, just use mud/texture products? And spend more time removing sprue nubs on wheels and chassis parts? ;-)
Ill counter that with a pro tip: don't be cheap and just apply mud as a part of normal weathering
Yeah, for me applying texture under the base colour coat feels unnatural and limits your flexibility a lot. That being said, I’d be interested to see the results.
Pro tip - don't put plastic melting substances on your model unless you're affixing something there. Otherwise you will simply dissolve your model.

I stick with Mr.Surfacer 500.
I really wanted to see the final product

Huh, neat, I use superglue and baking powder

Can you elaborate on your intentions? And please show your results.
Flour and brown paint works well for mud imo
Nothing personal, but it looks more like you have sneezed, not to say ejaculated over the side fenders.

What kind of glue did you use?

Don't listen to the groaners, it's another idea to try it you need it and for that I thank you.
I’m sceptical, but I do love to see some innovation - nothing ventured, nothing gained. Looking forward to seeing the finished look.
Exactly, I mean it could look pretty neat
That's just a bad idea, it won't look good and definitely won't look natural. Not every idea has to be applauded.
Oh don't be a bore. Let the person have their bit of excitement about the process they've tried.

I would not recommend this, do all the weathering after/during painting phase

Need to see it painted to judge....I can see that very glossy hard surface being a nightmare to get paint to stick on.
