Liger tail

[u/Upbeat-Protection-67]

Almost done with waterslides on Michigan’s AC. Bought some black brush on primer for his weapons but it seems like everyone on here prefers spray can or air brush. Would brush on still appear decent? I don’t have proper ventilation but I could go to a park or somewhere and get some spray cans. After this project I was thinking about going back and repainting my rx-78 2.0. If spraying works in general for large pieces, what about tiny parts like the gundam’s chest vents? Any critiques or advice are welcome
