Too many layers - how much can I wipe?

This is the time when I should have been on the Beara Peninsula. So yes, I am feeling sorry for myself.  I overdid it with layers, mostly Grey of Grey, and lost all transparency and granulation!

Layering

I didn't take a photo of all the muddy layers of gouache, watercolours, acrylic markers. It's like I'm trying to test how much this watercolour paper can take. A lot it seems. Gesso obliterates everything. I'm back to the same question as a month ago. Should I just leave this behind and go back to pure watercolour? Am I going around in circles? Time to pause.
