I say leave it alone. I used the walmart stuff on my ski the 1st time I done the hold and when I redone them 4 years later to install my new REVS everything was still on there strong. I actuyally distroyed the old 24-7 footholds trying to get them out. Then I done a test when I installed these.
I used all sorts of bonding agents as a test and found that if you prep it correctly then you won't have a problem. I ground the tray down of my superjet with 36 grit then layed a piece of glass cloth across a piece of 1 inch dowl rod. I used the 8 dollars a quart walmart poly fiberglass resin, I used a profesional grade of polester resin (well I ran it by the local fiberglass shop and he done it) Then I used the west system epoxy resin and if you work the resin down into the groves to make sure that all the air is out of the groves they all stuck. You if you took a hammer and beat the dowl rod off of the ski it tore a piece of fiberglass off with each one.
I also layed strips of fusor, urethane, silicone, 2 part epoxy, walmart fiberglass bondo and some other 2 part stuff I had. The fiberglass bumper repair resin was the only one that would break loose trying to pop it off with a chisel and hammer. the bondo kinda poped off but it took a piece of fiberglass went with it. So believe it or not that is what I found.
Ok polester resin haters can flame away I have my suit on
