I'm with you Bruce. IF and I have to repeat you should stick with a COMPLETE paint system, IF you are going to mix systems, at least do it the "bestest" way.
You can mix systems in such a way that it is "not as bad" as it could be. While you could mix systems and end up with a total catastrophic failure.
It is like using a charcoal resporator. It is NOT recommended to use one with isocyinate containing products. HOWEVER, I know, you know, that people will. So, I like to tell people how to use the mask properly to minimize the exposure. I think it is better than saying "NO" and not telling people how to use the thing properly.
That being said, I have to repeat myself.
Following the tech sheets of any given product will by the odds provide you with a better end product, PERIOD.
