Xencast PX60 to make mold?

Hello
I have made some molds of CS25 Condensation Cure Silicone Rubber

but since the parts I make in the molds are for cars, you want to be able to paint them in a safe way, this becomes very difficult as the parts become very contaminated with silicone from the moulds 

so my question is if it is possible to make the molds of px60 instead of getting away from the silicone?
if so, what should I use for release agents?
or is it possible to completely remove the silicone from the products made in the molds?

best regards Johan

You can make a mould from Px60 but you will need to use release agent each time.
