Title: Metallic paint issue stripes

Have you tried increasing the samples to see whether it goes away?

500 samples ... same result.

Can you send us the whole scene?

Oh - and you changed the samples of the material, correct?

I can try :)

And I did change material samples from 2 to 500, with no difference.

I believe this is due to a patterning created by the metal flake. Decreasing flake size and flake visibility should eliminate the stripping.

Yeah but then I lose the effect of the flakes which I want to show .. (even if it's smaller in reality) .. it needs to show different than the none-flaked paint from other finishes ................. is there any other way to get shiny flakes in my material ?

Perhaps you could try scaling down the model, or selecting different units. That might make the flakes generate differently.

A different way to get flakes is to load label with white speckles on a transparent background over the regular paint material and then increasing the label's refractive index to make it appear more mentally. However I don't think this way you could really get the clear coat finish..
