When my mate sprays cars in the booth, they have random worksafe checks that they are wearing their resperators.
the rules are quite strict and fines apply, worksafe wouldn't do this for no reason.
2 pac paints are harmful to your health........... PERIOD
As brought up earlier, if spraying at home, its not just YOU getting the fumes in your lungs. What about your family and neighbours?
There are panelshops around that rent their booths out, doesn't cost much.
I can give details of one in Bayswater, Vic, for anyone interested.
