When do I use Acrylic Finisher vs 4-Coat?

Angelus Acrylic Finisher is intended for changing the sheen while applying mild scuff protection. Originally it was used for holsters and dipping leather items to give a final sheen to the article. 

Angelus 4-COAT is a urethane based clear coat that is made for more scuff protection and for changing the sheen of the article as well. 

You should use Angelus 4-Coat if you are looking for a more durable scuff resistant clear coat for your articles.
