Any advice would b greatfull

Im going 2 paint some parts in my engine bay, ive had them lightly vapor blasted,

wanna give them a really good finish but as i haven painted anythin b4 havent got a clue where 2 start n how, lol

i take it i will have 2 use a primer, then paint followed by lacquer, but is there any processes i will need 2 do, like sandin in between coats?

Cheers jay
