I use IV Prep on the skin and then go around the edges of the pod again with it after placement. If I think the area is going to see a lot of perspiration, I add an extra layer of Tegaderm (because that's the tape I have on hand). But if you can get a hold of it, they sell Hypafix - which is the EXACT same tape already attached to the pod. It is great for increasing the surface area of the tape around the edges so that it holds a bit better. I haven't used Bard, so I can't speak to that.
Like Bradford, I can attest to Skin Tac wipes. I find them so effective that it's too sticky for my taste. I have trouble peeling the pods off 3 days later if I've used Skin Tac and it makes my fingers stick to everything I touch.
