Resin Kit

Do i paint a resin kit assembled or in their individual parts?

Now do i:
1, dry fit a resin kit and putty in all the gaps between different parts and then paint the model as a whole or is it
2, better to do the same thing, but then take it apart and paint them individually (which, correct me if I'm wrong, appears to be the conventional way from what I've read)

If i did it the second way, aren't i still left with some gaps which will need further filling in, sanding, and re painting?

Could someone please shed some light on this?

Go with #1. Get the main structure together, do any sanding filing or filling you have to do then paint. Nothing stinks worse than screwing up a paint job because you get glue, filler, whatever on it- and with resin, sometimes it's too easy to damage the model trying to clean it back up (don't ask how I know!) If it's a building, get the outside walls together and glued, and get the roof fitted. Then you can paint the interior if you like before you glue the roof on.
If there are small detail parts that would be hard to paint on the model they can be painted first then applied, but get the main body finished first.
