project painting not working

hi everyone I’m new to blender and having trouble with the projection painting - I can’t get the projection painter to cover the white areas you can see in the screenshot.
When I zoom in on the model structure I can’t see an error that would cause the problem. :no:

Wondering if any of you can see an error and what to do to put it right?

thanks
