hi all! im making a cnc positives to cast a mould using xpreg tooling carbon, but have some doubts on the finishing of the positives to cast the mould as perfect as i can.
i would like to polish the cnc machined piece as much as possible but due the work and the shape of the piece and importance on the precise dimensions, im thinking instead of sanding and polishing,
just paint the mould with high gloss car paint, oven cured, but i dont know if it will react when i cure the piece with the xpreg tooling materials, thanks
