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

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

     Depends how thick you want to make it? Solid PU for anything of any substance, other than a small lip spoiler, would be quite heavy and may need a couple of pours to avoid overheating and shrinkage.....

             The idea is that it should be hollow without a bottom and 2-3mm thick Something like this https://www.amazon.com/06-12-Lexus-IS250-IS350-Spoiler/dp/B00K3YFL66 I plan to make a 2 piece silicone...

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

             It worked well to make my roof spoiler Now the next project is 2 small front lips I thought I would make a 2 piece mold in fiberglass and that the final product would be 3-4 mm thick as the origina...

     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....
