Which type of mini roller for acrylic varnish?

[mct1]

I have sponge, mohair, longpile and the sponge with pink fabric-stuff around it. Which one would give the best result? I'm varnishing a refurbished desk which has been painted with acrylic paint (for that I found the sponge best).

From here:

If you'll be using oil-based paint, choose a roller cover made from natural fibers, such as sheepskin, lamb's wool, or mohair. You can also use a synthetic-fiber roller cover.

If you'll be using water-based (latex) paint, use a cover made of synthetic fibers.

Choose a roller cover with dense fibers. For fiber length, the rule to remember is the smoother the surface, the shorter the fiber length should be.

Also, see the recommendations for each roller type here. Even if yours are a different brand, I'm sure you can pick out the corresponding type.

I recommend mohair. I found the sponge left little dimples.
