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.

Through lots of personal experience, I would dispute most of what you have said. The Simoniz engine enamel (SIMVHT31D) is very hard wearing, retains it colour and finish well, it's easy to keep clean. It is highly fuel and chemical resistant but, if you have a continual fuel leak on it, fix the leak before it damages the paint. Follow the instructions on the can and it's perfect.

It's not my opinion . It's Science.
Spray can paint is just pigment lying on the surface
The. Original honda case paint was some type of epoxy. Fuel can be on it forever and it does not lift. It will discolor a bit.

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..

They have been using water as the solvent base on car body paint for quite a few years now, I've never had diesel or petrol strip the paint off when fueling as the paints are oven dried at the factory.

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.
