QUESTION ABOUT DURABILITY & ANGELUS PAINTS

Hey all---

I want to add more durability to my custom shoes. I find that my current use of all-surface acrylic paints and sealers are… well—laughable in terms of durability. They show small cracks at a moment’s notice, totally incapable of holding up to the flexing movement of walking in the shoes.

(As a woman, I focus on chick shoes, and the flats move and flex a hellovalot more than sneakers.)

I’m considering trying Angelus Paints. However, not all of the shoes that I go to paint are necessarily real leather. Will Angelus paint adhere to pleather or other synthetic materials?

If Angelus paints can’t adhere, would you recommend the use of the Angelus sealer over the acrylic paint to add durability?

Any advice would be much appreciated!
