how to flat black my 65

[FresnoFleetside]

I'm welding my rollpan on this weekend (at least I'm planning to), and since I'm gonna have to do some painting anyways, I'm thinking about going with a temporary flat black and entering it in a local rat rod car/truck show next month.

It's just a temp paint job, but I'd still like it to look smooth because "temporary" can turn in to a long time when it comes to my projects.

I've rattle-can-primered a few vehicles in the past, without putting to much effort into it, and it's came out alright. All I ever did was wash it, mask it, and spray it.

I was wondering if anybody had any tips on technique, since budget is an issue, I will still be using rattle-cans. So do I need to sand the paint first? Wet-sand? How many coats? How many cans? What kind of paint/primer? Should I clear coat afterwards, or will that make it glossy? Rattle can clear coat ok? and how will this paint job effect the next ghetto paint job I do later on down the road... lol ...

I know that's a lot of questions, I appreciate any help. Thanks for reading.
