Under dash painting

[Jcfcamaro]

Hello guys, I'm needing some advice on painting under the dash. I just got done epoxy priming everything but boy did I struggle getting everything covered under the dash. I have a devilbiss flg-4 gun and with the regulator and filter there was hardly any room to move the gun and get the correct angles to cover it all. Also can you mix the paint and clear together so I might have a better chance at covering everything in one shot
