I have a question concerning using lead based boat paints for accurate wooden scale models and safety tips. My friend and I have made small scale models using the standard model paints but also some larger ones with actual real "bottom" red paint, which contains lead. How dangerous is this? Also, some now, non-US nitro finishes for vintage guitars contain both lead and a flammability level not acceptable in my country. What is the best way to use such a finish on a guitar? Fender Musical Instruments used this finish and the dangerous bakelite process for other parts in the old days. The factory had a huge fire/explosion in the '50s and that killed bakelite for them. Not long after at Fender, nitro finishes were replaced by poly finishes. It is my understanding, in both boats and guitars, that the lead paints/finishes is only dangerous if you sand it into fine air particles, right? The PbCO 3s and 4s that are used in most lead based finishes/paints that use lead doesn't call for a respirator, but is that a good idea? And what kind? Mostly I smell fumes from most paints, lead or not.
