Once you get the adhesive off, I wouldn't bother with anti slip paint. Unless it's came a long ways since I did my garage floor in it.
Around 10 years ago I put anti slip tape on my dad's wood dock, and on the aluminum seat he always steeped on to get in his boat. It was still holding up fine when he died in 2021.
Something like this. They have large stripes too.
