One ton?? Geezus that's a lot of fumes!
When stationed in Diego Garcia, Avionics division (me) worked out of these "trailers/vans". Whole bunch of them connected together with shore power hooked to the sides. The air was extremely laden with salt (hell.. it was an island!), so there was a full time crew always chipping, grinding, and yes.. painting. They used the same crap as what was on the birds, and man when those fumes got into the recirc... it was bad.
