I whipped out the drywall spackling paste because I was having issues with a lot of difficult-to-sand little bumps in my paper mâché coat and it's working like magic so far.

I've used spackling paste to fix small patches in props and primed/painted without issues, but I'm a little worries about the whole prop being covered in it like this, especially because it's a big foot-level prop that's going to be dragged around.

Tldr; and suggestions for making a drywall-type exterior more durable without 6373663737x more work? Otherwise I guess I'll just prime and paint like normal and cross my fingers.
