These are just based on my experiences, I don't think there is a right or wrong way to paint, you just gotta find what works for you. 1) Always thin your paint! This is the biggest bit of advice I can give. 2) Pick a simple colour scheme and stick to it 3) Always prime your models, preferably with spray, this gives you the best base for painting onto 4) Experiment with different paint brands until you find what works for you I'll try and post a step by step guide maybe I'd there's enough interest
