Ap
In your two threads on this topic, you have meticulously defended your practices and thoroughly covered all conditions relevant to the application of this paint. You have responded to all comers, and have been fortunate to receive questions and suggestions from many of painttalks finest contributors. You have presented a rather bizarre scenario with multiple variables, and specious photo representation. Many of us have taken time to engage in what equates to a good game of pin the tail on the donkey.
You are open to no other possibility than the fact that you must have had a bad batch of paint. I suspect that most of us would likely agree. That is your story and you should stick with it. If you can't make it stick, at least all of this back and forth on painttalk has you well prepared to defend your stance against the worst case scenario, should it happen. For the love of god, read some other threads and take your mind off this, for your own good.
Don't forget, the whole benefit of selling out to Masco, is that they must bear the brunt of any fallout in this situation, especially since they required you to use the likely defective paint. You are a company man now. You don't carry the same burden of liability that you did in your self employed days. And, yes, I know, you are proud of your work and your reputation. Sometimes we all need to set the ego aside and realize that certain things happen that are out of our control. If all that you are telling us is correct, then this must have been the case. Keep your mind open to the possibility that if Masco relieves you of your duties as a result of this quagmire, it may be the best thing that could happen for you.
Good luck to you.
