Major mistake Number 1:
"…( halfords rattle cans), which are decanted…"
Just plain foolish thing to do. Dangerous to boot. Aerosol paints are formulated to work in an aerosol can, not in an airbrush, and acrylic aerosols are very problematic, especially metallics. They should already be thin enough to airbrush, which is why:
"…thinned with cellulose thinners…"
Is major mistake Number 2. How do you know cellulose thinners are compatible with the binder or the pigment. The results you are getting indicate that they aren't.
Major mistake Number 3:
"…i have also tried humbrol enamels thinned with white spirit…"
Ditto, ibid. White spirit is usually naptha. Use odorless mineral spirits—the only safe solvent to use with a metallic paint when you don't know the formulation
