Can you sand plastidip?

Hey all,

I spent quite a bit of time and I can't seem to find a straight answer to this question. Can you sand plastidip? I am making a foam pepper potts for my daughter and I must have used too much pressure while making certain pieces so I created "ridges" at the seams. The seams are pretty good and to fill in any gaps i'll use chaulk after.

For most of the piece I sanded down these ridges and then coated with plastidip. After one piece tho, I realized I didn't sand it enough, the ridges are still very noticeable. What would happen if I go back to sand these ridges now? So i'm not planning on sanding the entire piece, just these ridges. I'm just wondering if I'll create a disaster. I can apply more plastidip after but i'm just wondering if anyone has tried this and how it worked out for them...

Thanks!

 

I sand it, works fine for me.. then can respray the area..
