You'll need a brush to cut in any way, so just hit up the grooves with
the brush then roll the walls. As an alternative, if there are a lot
of grooves and you're not grooving on all that brushing, use two
rollers. One with a 3/8" nap cover to put the bulk of the paint on
and fill in the grooves, and follow up with a 1/4" nap cover to smooth
out the paint on the flat surface of the paneling.


There is no flat surface. The entire surface is cut with grooves
ranging from 1/16 to 1/8 inch wide. They look to be just over 1/16
inch deep. A lot of the houses here all built by the same company in
the mid-1950s all have the same panels in the basements. The two
roller solution sounds good. Will a 3/8 inch nap be enough for those
kind of grooves, or will a deeper nap be required?

Thanks.
