I found a guy selling lead weights on FB for $2/lb, which is half price of most karting shops: link. My questions:
Most places require them to be painted white, so I plan to take a spray can and go at it. Is that all there is to it, or do people recommend a different coating (e.g. plastidip or something rubberized)?
Do I have to worry about exposing my kid to lead? Obviously they will be sitting next to it, and I might take it on/off for practice vs race day, etc.
Is there a way to “seal in” the lead so that #2 isn’t a concern? Some google’ing for lead paint, it can be encapsulated with some kind of epoxy, but I’m not sure that would last in karting conditions.
