Hi,
I have skinned some car parts for my car using the XCR kit.
I have skinned quite alot of parts and have got to the final stage of finishing with 400-1200 grit sandpaper.
I am looking to speed up the process by using a sanding machine with the 400-1200 grit papers.
Which is a good sander to use?

Definitely spray, although I don't use a can. Cans are ok for small parts, but I would still highly recommend getting a 2k clear rather than just a single pack rattle can.
The idea is that spraying allows you to get the coating very flat, you don't need to do any harsh sanding to flat the surface. So while you could apply more coats of resin, this will mean you still have a lot of flatting to do. You can develop the technique to get the coating flat enough that you only need to flat it down with 800 or so, but I just always found it significantly quicker and easier to spray.
As for prep, follow the instructions for your specific clear coat, many of them are different. The ones I use most I spray at 320/400 grit. I have used some that wanted a 600-800 grit surface, and others that wanted 1500, so it depends a lot on the specific coating. If the paint you are using doesn't give you this information, just play it safe and go with 600 grit. Should still give plenty of adhesion and not much risk of scratches showing through.
