If you want professional-looking automotive finishes at home, a gravity feed spray gun is one of the best tools you can invest in. Unlike siphon-feed models, gravity feed guns use gravity to pull paint into the nozzle, requiring less air pressure and providing finer atomization. This makes them perfect for automotive painting — from primers to base coats to clear coats. In this guide, we’ll look at the best gravity feed spray guns for automotive paint across different budgets and needs.
