Hi

How You archive matte or satin finish to mould? Using Vinylester/polyester Tooling Gel.

Sanding wet or dry doesn't work, it leaves visible marks.
I've tried also sand/glass blasting, small parts can be ok , but on larger gives me bad blasting stipes/marks. Suggestions?
Is there some chemical?

What is your trick?

@ Hanaldo
Yes, but my moulds are for solid surface, that's the point why I can't use matte additive.
