is there any that you can get in quarts and in rattle cans? I don't have excess to a paint booth and if any touch up needs to be done is why I am asking. and does any one know what the roadster shop uses on there bays?

Most any AUTOMOTIVE paint shop has the ability to put any paint you're using into a rattle can. For obvious reasons you can't do that with catalyzed paints... but you can shoot most catalyzed paints without the catalyst and it will dry. Say you wanted to paint your engine block -- which isn't going to show dust/dirt etc... then it works fine. I wouldn't do that for inner fender wells etc and frankly there wouldn't be any point to doing it that way. They'd look awful and the paint would be "soft".
