Hello,

I am working on a mold in MDF which I will then use with the resin vacuum injection method with epoxy and carbon fiber fabric.
The surface on the MDF is perfect now after the cnc milling but lacks the surface finish to start molding. How do I not destroy the current surface layer as I prepare for casting?

Have bought Easy Composites:
Pattern-Coat Primer
Pattern-Coat Hi-Gloss
Easy-Lease Mold Cleaner
Easy-Lease Chemical Release Agent
GC50 Epoxy Compatible Clear Polyester Gel Coat

I will use laminating epoxy together with 600gr Twill carbon fiber fabric with a Divinycell foam core.

Some questions:
1. Are there any shortcuts or do I have to do all the steps with the products as above?
2. How long do you think this takes from CNC milled MDF to finished form?
3. How much will be spent on each product as above if the shape is 600 * 2200mm large
