I am trying to paint a Polyurethane shoe sole, what is ?

Question

i am customizing a pair of shoes. help would be great!!

Answer 1

you will need to use an adhesion promoter on the poly sole and add a flex agent to your paint. adhesion promoter can be bought at a local auto parts store in spray cans. Flexible bumper cover paint can be bought that way as well. Hope you can find your color. GOOD HUNTING.

Answer 2

You will need an oil based enamel because water based paints won't stick.  Scuff up the surface with sandpaper and apply the paint.
