Infenous sanding project and it just keeps continuing.

Greetings from sweat garage. I have sanded days in this same spot, here is just an example of how bad I’m in this but I have done this a long time after I stopped filming… I’m preparing my S40 BTCC Replica to paint. It will be black “matt” so the color try imitate S40 replica proto car.
I have used Biltema filler and tools on this, they are cheap to get and good enough for my purposes. I try to be innovative in the beginning and cut in shape one plastic scriber but it was a mistake, it should be metallic to work ☹
