Quoted from Pinfidel:I'm going to bed but logged in just to answer this.
As a painter, I would suggest you sand it down nice. Get it perfectly smooth. Go to HD or the paint store and by a paint roller pan and what's called a 9" lambs wool. The wool wraps around and gets locked into the block.
I found Home Depot sells this but it is a roller. Is this what you were referring to?

It sounded like you meant something else and that you use it like a brush.
