It feels invigorating to completely erase a finished painting! When my paintings come out dead, I take an electric sander and sand them down to nothing. This is another reason I love painting on wooden panels.

The leftover paint acts as a groove and I kinda like painting on a surface that is not completely white. It also fits my subject matter of aged or abandoned structures in urban landscape.

My underpainting sometimes turns out really tight. Depending on the subject matter I go back and forth between really loose and tight underpaintings. I wanted to be faithful to the form of this car but left the background less defined.

Painting with brayers opened up a whole new universe in front of me. When I paint plein air I still use brushes, but in the studio with larger panels, I don't even dream of using brushes.
Nowadays I stop sanding the original paintings halfway and leave ghost images.
I painted over these in a way that the ghost images showed through - they became the "under-underpantings."
By the way dried oil paint powder is toxic. Don't forget to wear a mask and goggles when sanding!
