First of all, sorry if this is in the wrong forum....and apologies for not posting the make and model in subject...it wouldn't fit.
If it's in the wrong place, then please move it....also I have done a quick search, but can't find anything specific about this, and am sure there are some experts in this field around here.
Anyway, onto the topic in hand.....
I am in the process of starting to repair and respray parts of my car.
I've searched the internet, and can't find much detailed help on this subject.
Over the last 17 years, I have repaired and sprayed my cars, but without much success of a good finish to the top coat, and am looking for advice before I go ahead with finishing my repair job over the weekend.
What I've done so far is as follows....I suspect it's not all correct, and would value your opions and advice.
I have rust patches, and I want the car to look prettier & tidier basically (don't we all?)
I have rubbed down the rust patches to the bare metal, using P80 "sand" paper (not sure it is sandpaper) so that there is a smooth surface to work to.
Where the the paint work is sound, and it dips where I have rubbed it down, I have used a small amount of filler so that the surface is "level".
I then have rubbed down the filler, first with P400 Wet and Dry paper to get a smooth finish.
I then used P800 wet and dry to make the surface even smoother and so that it blends in with the sound paint work, so that there is virtually no dip.
My next step was to wash the area with soapy water, then rinse with clean water.
I masked the area that I didn't want any overspray on.
I then sprayed over the filled and rubbed down areas with matching Primer, over spraying to the sound paintwork.
I have sprayed at least 3 coats of Primer.
Now is the step I am nervous about....what comes next?
Do I rub down the primer with P1200 Wet and Dry or similar?
Or, do I just apply the top coat?
Once the top coat is applied....what do I do then?.....do I rub it down with P1200?...if so, wet and dry?.....or just dry paper?
Do I T Cut it?
How do I get a nice shiny finish?
In the past when when spraying wings for my old Metro, I couldn't get a glossy finish :(
You help and advice is wanted, and will be appreciated.

800 wet sand the primer...youy can mist a coat of contrating colour on to use as a guide coat, so you can any dips or pin holes youve missed
sand it until the edges have feathered into the old paintwork
now key the old paintwork that you wish to spray into or over...id suggest a grey scotch pad with soapy water..or 1500 paper , just sand it enough to dull the surface
wipe down with spirit wipe....then spray it
if the end result has orange peel or dirt nibs in it , sand it smooth with 1500/2000 and polish it back to gloss with a good compund/polish

oh i forgot to say
any future jobs...try to avoid getting any metal/filler/primer wet any more than you have to....it absorbs water and can cause blisters at a later time

For things like this I prefer to use filler primer over the filler (usually amber coloured) as the first coats will be where you'll spot any imperfections, and these can then be easily rubbed off. Also useful to have some knifing putty around.
Then top colour primer, then top coat.
