I do not think SPI would recommend using some other companies activator, or hardener either, in one of their epoxies or paints.
Not true.

For years with my own base, I have told hundreds of people, use ANY automotive clearcoat activator in my base, if they did not have my clear at one ounce per Mixed quart.

Now, I would never say use my clear activator in PPG clear or any other clear as that is bad news as everyone has a different OH/NCO ratio that is not public knowledge.
Basecoat activation is different from point, there are a limited number of choices the automotive paint company's have as far as "Aliphatic type ISO's".
So that is why companies say, any activator from a clearcoat or SS urethane and never a primer type.
