Making a smooth mould from a grainy plastic part

Hello,

I'd like to CF-copy some automotive parts like rear diffuser, side skirts, etc. which are made of rough plastic with a grainy surface.

I may not sand the surface since I've to give the part back to its owner as is.

Do I need to wax the surface first ? How to polish it ?

What is the process to build a glossy mould from these kind of parts, in order to build aesthetic CF parts from it ?

I'd like to buy the materials from EC as soon as I know how to proceed Smile

Thank you all Smile

Ideally the plug should have a perfect surface but because most of the times you have to return the parts in their original state it's better to mold it as it is and then sand and polish the mold.

okidoki !
