An AMA newsletter recently published this interesting chart prepared by Mr. Jack Jella, displaying chemical compatibility of some finishing materials, commonly found in our hobby.

Example:

  • Vinyl Spackle IS compatible OVER polyester resin.
  • Vinyl Spackle IS NOT compatible UNDER polyester resin.

 

C   indicates compatibility.   N  indicates not compatible.
