Eddie and the slide

Does Eddie use a slide in "I'll Wait"? I always thought that was a whammy + slide combo coming out of the solo. Then I was listening carefully and was wondering if he was using it periodically throughout the solo. I know he used it on Dirty Movies and Could this be Magic.
Block Blast Magic Sound : Eddie Van Halen likely uses a slide in “I’ll Wait,” especially during the descending phrases after the solo, adding to the song’s distinct sound. While he is known for blending techniques like the whammy bar and slides, it’s not always easy to differentiate them throughout the solo. He also used slides in other tracks like “Dirty Movies” and “Could This Be Magic,” showcasing his innovative style.
Eddie has created a very distinctive style of guitar playing and on "I'll Wait" I always felt like his solo was 'rolling' on every note, especially with the use of the whammy bar. Sprunki
