I'm currently in the middle of painting my AoBR Boyz, and I've purcahsed a can of Chaos Black to help make priming faster and easier. Unfortunately, my first few candidates have emerged with their arm and neck joints covered with paint, and I have to file it off on each boy - sometimes, that's not feasible and other parts of the model may be in the way.
It has occoured to me that covering the areas to be bonded with some blu-tack would help, but I don't have nearly enough to throw away after the primer gets into it.
How does Dakka solve this particular problem?

Oh bum, I've gone and posted in the wrong subforum. How do I get the thread moved?

I may be a heathen, but I just glue over it sometimes. or just scrape a bit with the side of my hobby knife.

Blu-Tac or masking tape, depending on the size of the area you need.
I'd go with Blu-Tac on anything smaller than a tank

Aquaterry

I scrape the joints with my knife. I don't worry if I miss a bit of paint; plastic adhesive (not superglue or epoxy or any other adhesive, but actual plastic adhesive) tends to melt most paints on contact.

+1 to blue tac

I don't have any problem with my glue not sticking after I spray prime, but I use Krylon...

Oh and i have 100 boys and 20 of them are AoBR and I dipped them and store in a ziplock. No breaks... no chips

Blu tack as a mask and afterwards put it in a ball and stretch it continually and stick it back to itself. It will warm up get real soft and sticky and the paint should fall out of the blu tak. Blu tack is a great cleaning product and is self cleaning

still think that acryl-cyanate-glues will work fine over primer

It is? Brilliant, thanks a lot. I'll get to using Blu-Tack right away.

As doktor_g said, you could use super glue to glue the models together after priming with no issues.

Perhaps not the best application of the technique on your AoBR boyz, but in future modelling/painting projects it can be quite usefull to create a few sub-assemblies using plastic glue, paint them seperately, and then finish by gluing together with super glue (or CA, as some people refer to it as).

A great example of this would be a standard space marine from the tactical squad box. I would glue the model together without his boltgun, then paint the boltgun and marine seperatley, then superglue the boltgun onto the marine when everything else is done.

If you are gluing plastic models with plastic glue the glue will disolve the paint & get to the plastic without too much bother.
Use decent plastic glue = no problems.
Otherwise, use blu tak.

I've never seen paint "fall out of" poster tac (I can only imagine that happening with an incredibly thick buildup), but it does certainly get broken up and redistributed enough to effectively disappear, after a bit of kneading. I've primed about 30-40 models, using black spray, masking with the same small wad of tac and it hasn't even darkened appreciably. Besides, when it does eventually wear out, you're not exactly buying gold bullion.

One final thing here: for those that glue over the primer with any glue that's not solvent based, understand that your joint is only as strong as its weakest link. If you're using an adhesive over primer, the primer layer is now part of the bond. Is it strong enough? In my experience, no, particularly with metal or resin. This works in the short term when gluing light plastic pieces together but I don't personally use anything other than plastic adhesive in this case anyway...it's what it was made for, after all.

I was reading a thread last night where a guy professed to spending hours painting each face. If he can do that, I can spend a minute cleaning up a few flat surfaces on my models to ensure that they don't fall apart later. It seems like cheap insurance to me.
