Stores that sell PPG auto paint has the hardener.
I don’t use the hardener in the engine paint but I do in the frame paint.
I have a tendency to not use the venders paint because I don’t know where they get it from and if they change suppliers/types, I won’t be able to match it. I got the color off of an engine and had PPG formulate it for ALK-200.
I’m told it’s just about as hard either way but without the hardener takes longer. The hardener only makes the surface harder. Also there is a difference in drying times.... see the data sheet.
I like it as a frame paint because I can do touch ups with a small brush. And I can paint the tops of the bolts I’d needed.
Blending Is a little tricky if one coat has the hardener and the other doesn’t.
