I do a lot of painting and I never use a 1/4" roller. In fact, I always use 1/2". Was it an off brand? How much did you pay for it? Did you prime the wood first?

The roller is from wal-mart 6.70 for 3 yes the wood was primed then sanded then two coats of white finish I went to the roller to not have brush marks

I've used 1/4" nap when rolling oil enamel on slick surfaces but I use a mohair cover.

What brand of finish paint did you use? Did you sand between coats of finish? Were the air bubbles apparent while the paint was still wet?

When it comest to painting, I buy good stuff. Cheaply made rollers and brushes make a job twice as hard and quality made products make the job a breeze.

I would use sand the surface with a fine sand paper on a small sander. Then buy a Purdy or Benjamin Moore roller in a paint store.

What coating are you applying? Cheaper/low-quality coatings can also cause issues like that.
