it could change the leather texture.
I texted my SA and asked whether she can recommend anything. She doesn't suggest spraying it as the ones she knows on the market have chemicals no less so she is concerned about staining.
I'm just thinking whether ph balanced products like Loving My Bags products will help? I apply their leather protectant cream on all my cuirs and so far okay. Used it on the Pebble cuir too. But 3D is another leather type altogether. You might wish to drop Barbara of LMB an email to check?
