help, suggestions for painting an old bike needed


i am restoring a bike from the early 60's, i have sanded it down to the metal
using 60 grit, then 120 grit, then 220 then 400 grit sandpaper so right now its very smooth and clean.

The questions i have is some say to only sand to 120 or 150 grit before applying the first primer layer and now i am confused since others say to sand to 400 grit. Which is better or correct?

I also read somewhere vinegar is a good thing to apply before painting the metal, can anyone attest to this or suggest what to do?
i assume you just wipe it down and let it dry.

I am doing everything with spray cans,
step 1 - self etching primer, 1 layer
step 2 - sandable primer
step 3 - sand with 500 grit
step 4 - sandable primer 2nd coat
step 5 - sand with 500 grit
step 6 - paint first layer of paint
step 7 - sand with 1000 grit
step 8 - paint second layer of paint

is this enough to assure the paint will last over time?

also if vinegar is good for the bare metal surface, what is a good cleaner
to use between the primers and the primer and paint layer?
just warm water and dish soap and rinse?

any suggestions or thoughts on painitng metal would really help me out.

thank you

I'd check out some sites that deal with autobody painting - it's pretty much the same deal. Just be aware that you'll never get as nice a result with a spray bomb as a professional will with a spray gun. Perhaps you can follow all of your steps to prep and prime, then take it somewhere to get it painted?

Can't say I've used vinegar to clean metal before painting, although I've used it to clean windows! It would probably work, but what is gauranteed to work is rubbing alcohol. Cleans up any oil from your fingers and leaves no residue.
