I'm building one of the Knight Armiger Warglaives from the Forgebane box, and it's the first time I'm really doing something in sub-assemblies I'll paint first then glue afterwards. In this scenario, where I'll likely be connecting two painted surfaces, are there some glues that work better than others? Or do I really need to just sand down to bare plastic in limited areas before gluing together? Recommendations for both products and techniques would be appreciated, thanks!!!
