Hello all,

A few posts ago I read about someone using Spackle as fill-in on his wings.

Isn't spackle brittle?  Wouldn't it crack with flex?  It seems heavy, too.

Are there any other materials that can be used that are light and flexible?

What about that spray foam that expands.  Could that stuff be sprayed out, 
then applied to the work, then let to dry? 

Please advise us all !
