Hammertone Texture in Metalflake??

[Bob B.]

Hi all,

I'm looking at a guy's paint on his C1 and it is silver metallic, but it looks like hammertone to me. Pics are attached. I can't remember seeing this on C1s before, but maybe I wasn't paying close attention. But does this look okay for judging? If not, what caused this and can something be added to the paint to prevent the hammertone effect? This is modern lacquer.

Thanks,

Bob

Bob,
I sprayed metalics from the first day they came out. That's not the way it is supposed to look. It looks like it was sprayed on dry and then gloss coated.
Spray gun pressure and the incorrect mix will also do that, or ones first spray job.

Dom,

Thanks for your response! No gloss. He has done sanding with 1200 and 2000. What pressure would you recommend and would you think adding more thinner would help? Also, would you use a faster or slower reducer?

Thanks,

Bob

Bob,
As all the painters will say, there are many factors involved when spraying paint.
The brand spec sheet says it all. Pressure, temp, humidity, distance from car,m and fan width.
Usually about 55 psi on the conventional guns is about what they want. A wet enough fog coat (thin) then a time period which I ignore and do a finger test on the tape. On metalic it's easy to se tha spray pattern if the gun is to close or the fan to small.
When I get my last coat on & wet I usually open the fan and blow the metalic on even so it doesn't show the pattern you used to apply the paint.
Air pressure is REAL important when match painting metalic. The pressure and viscosity will cause the metalic to be deap or near the surface and that will effect the amount of pigment that is seen.
Laquer will rub out just fine using 400 grit. Not so with the modern urathane paints, they need to be sanded in the 2,000 range.
