Water borne paints are catalyzed
McCabe-Thiele (Ted):
Do you know the chemical name of the Catalyst they use?
Is it not likely that the same or a similar catalyst is used in Simonize Engine Enamel?

This is an interesting background to the complexity of paint technology, I will not even go down the route of what surfactants do as I have never fully understood them.

Putting the Cases in the oven to "cure" is a waste of time and energy. It does not make the paint any more durable or chemically resistant. If you want a paint that will withstand time and chemically resistant use an Epoxy or a 2 part paint with a catalyzed property
These paints cure via chemical reaction and are durable for the long haul.

Simonize VHT is an Enamel paint, heat curing at the specified levels drives out all the solvent so I disagree with your wide ranging conclusion.
You could argue that if your 2 part paint is not a 100% eutectic mixture the catalyst action might fail. There are enamel engine block paints that will self cure over time without the need for oven baking to make them petrol proof.

99% of the solvent s flash off in 24 hours naturally.
I can guarantee you this paint if left out in the elements will oxidized and degrade within 5 years if left out in the elements. And drop some acetone on it and it will immediately dissolve..

There is no worse storage for bikes than a typical UK brick built garage in the winter, the Simoniz stays perfect and shows no sign of oxidation after many years. As for acetone, why would you get that near any paint, that's just asking for trouble, the same as if you dropped battery acid on paint?
The main point is that a good quality enamel paint out of a spray can gives an excellent finish and is very user friendly for the DIY'er, which most are on this forum.

I was just using acetone as an example.
I totally agree with you about us DIY'ers. As with most of our bikes not are used for fair weather riding and poop cams are the way to go.
But the baking in the oven adds nothing.
