Top Coat On Horween Dublin Leather

[rmr]

So Im making a briefcase and am using Horween Dublin leather ( has a pull up effect)- very beautiful leather. My question is: with the horween dublin leather is a top coat needed?? Will a top coat such as neutral bag Kote or Tuff coat effect the pull up properties of the leather??

Thanks you

For what its worth, I have a change purse i made out of chromexcel and to experiment, I put on 2 coats of 50/50 resolene on the grain side, flesh is untreated. It still has pull up, and changes colour when it is full of quarters, then goes back when empty, but here is the kicker: I have accidentally run it through the washer and dryer several times and it appears just fine. No change at all, except for some rust on the snap spring.
