The TAT website says 2-in-1 primer but does not say what it is.

They also say "They are compatible with virtually all automotive paints."

I asked the question (above) because having a 2-K spray can seems impossible.

Considering the cost of quality exterior paint, and the time and effort taken to prepare the surfaces for painting, I'll keep using small batches of DP primer from PPG as long as I am using PPG DCC as a top coat.

TAT's Technical Data Sheets have no information about the composition if the primer.

TAT's MSDS sheet indicates that it is solvent-based product (not a 2-K product).
