Always refer to the manufacturer's instructions as they know for sure, but assuming its a regular air-dry primer like a cellulose, synthetic enamel or acrylic base then 20 minutes or so in a reasonable temperature. Obviously they dry a little slower when its cold and a little quicker when its hot.
I understand Rustoleum takes longer. Never used it.
If its a 2K type primer then its all down to the activator you use in it.

if it clogs the paper then it's to soft so leave it a bit longer
or just take it to a body shop and have it done properly before we all go bust

ok , as alistair said , refer to manufactors details , the norm is , 2k primer and cellouse can be painted over within 30 minutes if the items are low baked at 20 deggrees celsius first. if the panels are left for a few days then the need de-nibig with 400 to 600 wet and dry , use a flatting block so as to not put ridges into it from your fingers , if the papers clogging then use a good quality bar of hand soap to help with the flatting. also before flatting dust coat it with upol dust coat , this allows you to find the highs and lows when flatting. the key to success with all painting is good prep first. don't rush it , ade

if it clogs the paper then it's to soft so leave it a bit longer WHS. I like to leave cellulose overnight before sanding where possible. Its soft paint and it cures slowly. I would get all my primer on and then the next day sand it gently with a P320 or P400 to denib it. I would only use something as coarse as P240 if I was putting more primer on. If you arn't sanding the primer before painting the gloss then 20-30 minutes is the window. |

I too leave it overnight minimum - but that's cos I usually spot the mess I've made of the initial flatting  I also go to 600 for the de-nib, but I'm a northerner and am just too tough  Good luck....... |

another thing with celly primer...make sure its parked in the warm and dry until its painted ..otherwise the primer will soak up damp and cause blisters later on

opinion is divided on this topic. Some people swear by it, but others cite the risk of getting water soaking into the primer and causing problems later on.
I don't use wet sanding on primer personally, although dry is hella dusty.

the paint will be dry to the touch in 15-30 minutes, depending on paint, coat thickness, how you mixed it, ambient temperature, etc. but dry time is not the same as cure time.
For cellulose and similar products you should leave it 48 hours really, and some people say 7 days, before colour sanding and polishing. This is for two reasons - 1. the paint remains soft for a while even when dry to the touch and 2. solvent continues to rise and evaporate meaning you can cut & polish to a beautiful gloss and then find 2 days later its all gone dull again. This is one of the big reasons bodyshops moved on to catalysed paints like 2K as once its dry, its stable.
