VEVOR Airbrush Spray Booth, Portable Hobby Airbrush Paint Spray Booth Kit with 4 LED Light, Powerful Dual Exhaust Fans, Turntable and 6 ft Extension Hose, for Painting Models, Arts, Crafts, Cakes

I find it hard to get even coverage on large pieces without spraying (rattle can or air brush), so I keep the hand painting to just small details and inner frame type stuff. Maybe something like this portable spray booth might help: https://a.co/d/0jilTh8i
