Default PVA glue and primer

Hi guys.

This probably sounds really silly, but wanted to ask anyway.

I've gone about basing the new force differently for the army challenge, where I apply the sand to the base and seal it first BEFORE I lay down the primer to the model.

I used a scenic cement style approach to sealing the sand on the base, dunking the base to cover the sand and letting it dry. During the dunking process, obviously a bit of PVA glue has gotten onto the feet and some of the lower parts of the legs of the models, and it's obviously drip drying as we speak.

My question is, will any traces of dry PVA glue on the legs etc cause the primer not to stick to the model? I'm thinking it will be fine because it'll obviously stick to the sand too, but not sure because it's plastic, not sand.

Like I said, it's probably a stupid question, but one I wanted to ask anyway.

Thanks for reading

It would be best if you could remove the traces of glue before painting. Wait for the glue to dry or else you might just smear it around and make a mess. Being pva, even a good rub with an eraser may budge it. Otherwise get the tip/point of your knife and perhaps pick it off (or try the chesil it off approach if there's space). PVA will tend to try and come off as one-piece which is good. If you can get a corner up, you should hopefully be able to peel away the rest (including any whispery strands).
I wouldn't go introducing chemicals as you've already got other parts sanded and done unless you protect those areas with some masking of some kind (you might wanna protect the areas anyway seeing how you may be taking a knife to it).
I wouldn't try sanding it down. The surrounding area (the model) may end up getting sanded down more then the actual glue spot you're trying to remove. I think pva kinda clogs sandpaper and would come off in clumps/chunks after using a course grit paper.
Perhaps a pic would help illustrate your situation mate.
Hope it helps mate.
