Here is the deal:
Urethane is far, far better than lacquer! That is why the entire auto industry has switched! Paint your car with lacquer, and it will die in 1/3rd the time that the urethane will last. In cold weather lacquer will crack, and in hot weather the gloss will die. I'll attach a before and after picture of a PPG lacquer job. This was a Street Rodder cover car, but the owner had limited garage space, and it sat outside for 18 years.....and this is good quality PPG lacquer!
Isocyanates build up in your body, and it can not get rid of them. The day will come that you will have a reaction, like your throat swelling shut, which means your body reached it's limit. I have several friends who this has happened to, and it means you are done painting! The next time you use it you can die.
You do not normally use a catalyst in anything except the primer, and the final clear coat. A few painters do, but it is expensive overkill.
I have been told by more than one expert that a charcoal mask will not protect you from Isocyanates. They will go right through it! Do you want to risk it?Last edited by HOTRODPAINT; 08-09-2007 at 03:57 PM.
