the one's i've made i've dipped in the rubber tool dip. the same stuff you dip your tool handels in. It works great, there is just one downside, the paint isn't very bright, so on those dark mornings when it's light enough to cast the paint isn't really bright enough to see. Sometimes during this time i will add a little florescent tape etc. to the float and charge it with a flashlight. The other thing i've done (just recently) is to paint it with a bright color (of your choice and paint type) then when it drys i've used some boat epoxy to cover the paint. this stuff drys hard and the paint doesn't flake off (i've had the same experience with the flaking paint) the only reason i tried this was because i was working ona boat i'm building and had some left over epoxy that i couldn't use at the time and some dink floats were sitting there so i just painted it on them. the epoxy is by System 3, it's very expensive and if your price oriented it's not really worth while to buy it just to do Dink floats, but it worked great. Hope this helps.
