Hey, new modeler here and this is my first post.
Modelling is a waning market in my country and I don't have enough options for a gloss/metallic primer (due to them simply not being available) specially manufactured for model kits.
I've seen from some searching around about plastic crazing... I do have an AK primer (matte). How can I top it with a layer of non-model kit primer (that is first layer is AK, then this) to follow with candy paints? And can non-sandable primer be sanded (I have 600-2000 grit sandpapers).
Have a good day,
PS
