- Make sure the paneling is clean of dust and oils
- Prime it with blocking primer
- Tape off and windows, trim and other areas you do not want to get paint on
- If you do not want the grooves, fill them in with compound or spackling. Dry and sand.
- Now, paint away.
Give your room ample time to dry and then remove the tape very carefully. Wipe up the edges if there is any paint over flow, and then restore your room to the way it was, and now enjoy your handy work!
