In the shops that I was in we used all brands of auto body paint. I'm not against these products I enjoyed the auto body trade . I just feel that they are for the spraybooth with the right safety gear.Not the home garare/carport/shed/etc
All the old tech paint/primer/clear coat had Iso cynates in the hardner/activator.Auto body products were made for the auto body trade not for the back yarder.
Some old school paint and primer had lead and mercury and other heavy metal in them. So when you sand/grind paint
on your car the lead becomes air born as well as what ever was in the solids.
Auto body old tech two part/component paint/ primer/ clear
You have your paint that is made up of solids, pigment,binders,etc
Then you have your reducer/solvent
Then you have your hardner/activater = iso cynate
Last time I was in a body shop was two years ago and had a good discussion with the guys head painter,prep man,and manager we talked about the new water born paint and were the trade was going. They said that the clear still had iso cynate hardner.
I do not know what primer/paint tech that you are using new old?
I do not want to hijack your thread. I like your build and Thank You for what you are doing for the G body community.
Good luck with the rest of your build.
