And now for a tirade-
Here's a HUGE time out. First, there's been a bunch of "activists" that are hitting up forums with dramatic, unfounded accusations about the hazards of fiberglass insulation, composites, etc. Which looks a whole lot more like stoking up fears about certain industries, likely for economic and strife purposes.
Having said that, and let's PRESUME for the moment that you are legit, let's discuss these potential "hazards":
First, there's no lead content within epoxies, polyester nor vinyl ester resins. It serves no purpose there. There is a possibility of lead oxide in certain color pigments, however these make up a minute fraction of the total volume of material. Additionally, such lead products have LONG been illegal in the US, though Chinese companies still foist the cheap, lead painted stuff on us all the time (see the massive number of stories about this online).
Ok, next- IF there is any lead in an epoxy or ester matrix, it has to be available for exposure to the individual, and second in an amount that matters. That typically means sanding the material aggressively then breathing or ingesting the material. Then it matters what type of lead it is as to whether it's biologically available to the persons body. For the type of boat maintenance activities we deal with in the US, adults have a very, very limited exposure potential.
And, then just because "it's chalky" has zero bearing on whether gel coat is a problem, nor whether it has any lead issues. It's gel coat, not house paint, which had WAY larger quantities of lead oxide. The chalky in gel coat isn't due to lead. Buffing and removing the oxide is not a health hazard. Lead Oxide is sweet to the taste and was a problem for kids, who are particularly at risk, much, much less for adults.
I've gone on long enough- you want to discuss proper monitoring and hazard assessment, not just taking a portable XRF to take "pictures" of crap or just make up drama, then we can go there, but coming on forums and fear mongering is absolutely irresponsible and an obvious lack of common civility. And, if you have somehow got your hands on a portable XRF and you're going around "taking pics" of stuff to find a problem that probably doesn't exist, it's even worse. After All, there's a whole lot more lead in your cell phone... And, are you sure you don't have some interferences? And, finally what readings did you get? Next, how do these readings correlate to either airborne or ingestion concerns?
