Putty

Hmmm;

 I'll have to try this stuff ;

Perfect Plastic Putty, great stuff, no health issues. Like any it dries a bit in the tube, so keep a bit of water close by and put a DROP into the tube top , stir and it's reconstituded. Sands great, no shrinkage that I have noticed.

Also Tamiya white works well, I don't notice a smell, worth a try.

I'll second Bruce on PPP.  Have started using it, and really like it.  Damp Q-tip to clean up excess, and the small pointy Tamiya Q-tips work well on tight angles.
