bobs205 0 Posted March 30, 2006 What's the best air pressure to be painting my bonnet with because i've got 120psi in the air line's which i think is a bit to much to blow paint on with? Share this post Link to post Share on other sites
mike parsons 0 Posted March 30, 2006 If I remember correctly: 120psi is ~ 8.25bar. Average workshop compressed air systems operate at 7 to 10 bar, with a filter/regulator reducing the spraygun pressure to around 3 bar / 45psi. Hope that helps. Share this post Link to post Share on other sites
Paintguy 0 Posted March 30, 2006 Very much as above, but it does depend on your gun, setup, paint, and conditions. For a 'normal' gun 3 Bar is a good starting point, for a HVLP gun, start at around 1.8-2.0 bar. I could go into how to set your gun up before you paint, but this article explains it much more eloquently than I ever could. The first part is mainly about HVLP guns, but the second half about the actual tuning of your gun, applies to any type. Share this post Link to post Share on other sites
