Actually we do package it in an aresol can for home restorers.
In the aresol it is not as glossy as it is out of the gun and takes longer to cure.
One it is brought up to operating temps on a motor is is very durable.
You would have to buy a few cases to make it worth while to do a custom color.
We normaly only package it in vintage mopar engine colors.
