Sounds like it may need to be thinned or you may need a larger tip on your gun. Primer is usually pretty thick stuff.

I was going to say the same about the gun tip size. Primers usually want 1.4 - 1.7 tips.

Is this primer an epoxy or high build primer?

What type of gun and what air pressure are you running? And how are you measuring that pressure? At the gun tip or at your compressor?

Have you shot successfully with this gun/compressor setup before?
