flo coat is gel coat with a wax additive to make it go off in open air (gel coat normally needs to be shut off from air to set).
If you get the cfsnet catalogue, it explains it in there. You can buy premixed flo coat from them which saves you having to faff about adding wax. It works well and produces a very hard wearing coating however it is a matt finish so its best to apply it using a foam roller to get an orange peel effect.
JW, no idea quite what this dispenser thing is you talk of, but they sound better than the syringes! I use gloves to protect my baby soft hands
