What’s the difference between a knife grade and a flowing grade polyester?


The knife grade has a thicker consistency, similar to peanut butter. Flowing is more liquid and flows easily. The knife grade is good for filling holes over 1/8 of an inch. For smaller holes the flowing grade will penetrate better.

TIP Most polyesters have a limited shelf life. Do not keep any polyester for more than one year.
