HELP with bodywork

Most spray bombs are cheap lacquer based products and don't have an activator/hardener so it's a crappy foundation. To make it worse there isn't a heck of a lot of product in a can so in the end you will have spent more than if you bought the good stuff. There are dsicount brands out there, Omni, Kirker, etc. It isn't easy to do this without equipment and space to start with, let alone cheaply if you want a decent, durable job.
