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... Unsure
