A lot of folks worry about this and they really needn't get so concerned. Most of the major boat and mast manufacturers, have been building rigs with stainless fittings, track, etc. with no insulation and get 20 years of service out of it. I've personally replaced and repaired 30 and 40 year old rigs, built like this and some corrosion can be seen on the worst cases, which typically are moored or berthed in salt water, but for the most part, it's not something to get all fuzzy about. If really worried, a Teflon washer under each fastener, can solve the concerns. As to this particular paint, well I don't think paint is well suited at this task, unless the film thickness is quite a bit thicker then typical. A well dogged fastener can easily breach a paint coating as it's tightened. The edges of the hole in the track, are often raised and this will likely breach any coating, when a fastener mashes it against the mast.

I currently own an aluminum hull boat and this has been the topic of many discussions on our forum. One of the things that comes up frequently as an "easy" way to limit galvanic corrosion between aluminum and stainless fittings is tefgel.
