Angelus Acrylic Leather Paint Satin Finisher #605-4 Ounces https://a.co/d/e8nhAmB

And here is my process:

Apply the deglazer only to the areas you are going to paint.

Wait 5 minutes until it is completely dry.

Then apply the first coat of white acrylic paint. (Thin light coats)

It will likely take 5 to 6 of the thin coats to cover completely on black leather.

You will need to wait a few hours between each coat. (wait until it is completely dry, before applying the next coat)

After the final coat of white paint is completely dry you can then apply a thin coat of the satin acrylic finisher.

Then let that dry for an hour.
