Hello
I want to cast a small spoiler for the trunk of my car and thought to do it in polyurethane
Which polyurethane should I cast the final spoiler in?
I thought I would make the mold in silicone

Excellent! Glad it worked well.
As an alternative but tougher, you could use the
Xencast P6 Toughened Polyurethane Resin
but it is a bit more moisture sensitive in mixing and a little bit less user friendly than the P2. You could add milled carbon to the P2 to make it tougher. Both resins can be painted.

The pot life of most fast cast PU's is going to be too short to use a machine like that. Just ensure your mould has good vent holes and you should be fine.

The machine I linked to has 2 separate containers one for part A and one for part B and then they are mixed together 50/50 in the nozzle. Can it work on, for example, Xencast P2 Fast Cast Polyureth

You'd have to try it. These resins have not been tested in automated machines like that.
