problems with patchy metallics
 
I have real trouble trying to get metallics to come out even. Things like silvers, golds and light metallic colours are a real pain for me. When i spray a panel i can never acheive a perfect finish with the basecoat (either solvent or waterbase) and it can vary from a couple of light or dark areas to a completly blotchy or patch panel. I just dont know what i am doing wrong!

i spray at the same pressure (about 40-50psi) for all my paints but with pearls and solids i dont have a problem. I have tried spraying it wet and dry. If i spray it wet i get 1 or 2 really dark areas where it looks likes it gone too wet!! if i dust the paint on and it feels like sandpaper before i add the clearcoat which worries me to think that it may lead to delamination. Dusting leads to more patches but the difference between the light and dark areas is not so great as when i try and do it wet.

Can anyone suggest a proper technique to spraying matallics??

Flip your cap and try to spray. If the pattern shifts your cap needs to be replaced. If pattern ramains the same your fluid tip and needle need to be replaced.
