Does anyone know of a strong white glue that can be sanded. I always used Pica Gluit and as far as I know that product died with Pica.
Any suggestions would be appreciated.

Most Alphatic resin glues will sand easily ,not all are truely white while we call them white glues . Sig sells a true white alphatic resin wood glue that works well , dries quickly and sands easily. You would get equal satisfaction from any of the top brand alphatic resin wood glues available from any lumber store , hardware store, or Walmart.

Titebond II may not be a white glue, but it sands easily and smoothly. As does Locktite woodworx (exactly same as Titebond). Elmers white glue dries clear and sands reasonably well and can be purchased anywhere.

Titebond 3 is harder to sand then titebond 2 which is drying in orange color.
