Hi Guys,
I've just experienced my first mold making using Uni-Mould system. My project it to CF copy the "B Pillars" covers of the VW Golf 6 car.
These parts are made of plastic, with a glossy black finish.
So I made a mould this way :
- 4 layers of EC Chemical Release Agent, 30 mn between each
- 1 layer of Model 6 release wax, buffed.
- 1 coat of Tooling GC
- 2 slices of 80g CSM with the Coupling Coat
- 2 slices of 450g CSM with the Tooling Resin.
Demolding was quite straight forward.
Here the problem :
To restore the initial gloss of my part, I used EC Mould Cleaner and lint free wipes to clean the part surface, which was initialy covered by the release agent.
But all I get is a kind of dull, even whitish in some places, surface. Can't get my gloss back. What happened ?
Thanks for helping, I'm afraid I have damaged the part surface but don't know why... as if the release agent, or the mold cleaner, had attacked the gloss...

I use wax all the time for stuff that's not going to cure in the oven. 3 coats, no PVA. I use semi permanents only for prepreg work, they are way too expensive and a waste when not used to their full potential. Don't get me wrong, they work perfectly for this, but its over engineered. If you were using epoxy gelcoat and vac bagging, maybe.
