A couple years ago when I installed my footholds, I used 5200. I sanded and wiped with acetone both the footholds and painted surface of my ski. When I removed the footholds to inspect some hull damage, I found that the 5200 didn't stick at all to my holds and had been letting in a little bit of water. I only used one layer of 4oz cloth around the edges, which didn't help much. The holds came out super easy once i drilled out the rivets. The 5200 on the gunwhales adhered normally. The footholds are Blowsion Kickers or Diggers. Just thought I'd post what I found and see if anyone had any input. That was my first foothold installation. Next time I'll just use West System and 404.
