Hey. Delta Magnus here. I'm thinking of going into customizing Transformers. I've never tried it before, although I do play Warhammer 40'000 and have done a lot of modelling. I was thinking it might be best to start small with the actual Transformers themselves, perhaps just repainting them into a new scheme, or something like that. I was also thinking of making some accesories and weapons for some of my 'formers to wield. What would you guys reccomend as a first step, and what materials/components/paints are best for converting Transformers?
