How much paint do I need?

[Sad Sack]

@Sad Sack yes functionally it works, but it makes it hell on earth for the next guy if they wanted to paint it properly.

To the op:
I’d suggest at minimum using a quart/gallon of enamel and spraying it with a spray gun versus spray cans. Even better to use some hardener, that will improve it a little more too.

Or a lower end single stage urethane would be a big step up over oil enamel.

Well yes, the next guy would probably be inventing new cuss words trying to revert it...
If on a really really tight budget, I be renting or borrowing a portable air compressor, buy a cheap siphon gun, water separator and use Duplicolors PaintShop RTS and hope for the best..

I use POR-15. First prime it with their base coat good. Light sand between. Then Top Coat it in whatever color they have. I use white because it hides a lot of imperfections. Then light sand again, and a clear coat top. TAKE YOUR TIME. Blow it off with a compressor between coats so you don't have dust on it. It takes a lot of time. If you're going to do it in your garage, poly EVERYTHING that you don't want paint dust on. Close the door until it's just open enough for 2 or 3 box fans to fit, and turn the box fans on to take out the clouds of fumes etc. Wear a PROPER mask (3M is good) and have fun. It won't be perfect, but it will be good. It's an ultra cheap down draft paint booth. Hokey, but it works. DO NOT use a roller. LOL. I did once and it was REALLY BAD. Orange peel everywhere. Hope this helps.

Imho, hosing down a truck with bedliner (whether it be a professional job or spray cans) devalues a truck by 100%.

Certainly doesn't help that's for sure. Only something I'd do if I didn't give a rats a$$ about resell value...adds too much weight also.
