I have painted a number of frames with this detail spray gun from Harbor Freight tools. https://www.harborfreight.com/adjust...tail+spray+gun It works fine for a $14 spray gun. I use base/clear paints from TCP Global. Spraying the base is pretty easy and there is not much chance of runs with that. The clear is where you have to be really careful not to get runs.
