I could not figure out out what you were or who but this is coming all together now.
Let recap:
Paint companies are having an activator problem: (you)
Sorry, bull chit, if you know how activators are made, it is not paint companies but "Paint company" Period.
I was an expert chemical witness lately in court. (you)
And your first test was with a foam roller????
I have a salt booth. (you)
In 30 years have never heard that term from a manufacturer, I don't have one but I do have a cabinet.
I bought self etch primer from SPI. (you)
Sorry SPI stop making self etch 5-8 years ago.
You really don't know the difference between epoxy and self etch, do you?
It was also you that recommended a urethane primer for coating a frame.
Now for you question, will self etch creep? Glad to see you were on the spi forum and reading about the salt spray test I posted, its a good education, that you will never get from people that DON'T make there own stuff but have it private labeled for them with no spec's, just a price worry.
Why don't you answer the question, MR professional witness and I will be happy to correct you, as you stumble and try to make things up, as i have 10,000's of hours on a wide range of products, including pictures that I have tested over the years.
That post I did with pictures on the SPI forum must really confused you, especially the one with the 2K primer, that you recommend for frames.
Maybe that is why they call boat bottom paint, "Urethane primer"! LOL
Like I said at the very beginning, life has kind of passed you by, try getting a hobby or a girlfriend, might make you a better person.
