What colour is the car mate? Depending on the colour is depending on how the finish will look, some colours fade a hell of a lot more than others, so blowing them in is tough as the new colour will be more solid...
If you sprayed a whole section then you'd have the problem of it looking different from the rest of the car.
Mirrors, remove and paint them off the car mate...
The doors, tape off the sections your not painting along the contour lines of the car, with E30's, you have the ridge at the top of the door that runs through the whole car, tape along this and try to blow the paint upto this point, but dont allow the paint to build up too much in one spot else you'll see it majorly.
If its below the door strip, remove this and tape and paper up everything above it. Then when its replaced, the black door strip will seperate the paint work.
Sand back any rust and use some rust treatment product on it. Use 120 grit paper to take it back, then work up the grades... So 240... 600... 1200... Between each paper, try to sand out any of the scratches the previous paper has made, if you dont do this, when you get to grade 600, you'll releasise there is still deep scratches from the 120 grit.
Once all prep'd up, use the rust treatment on baremetal sections, then primer, between the coats use some 1200 grit or higher wet and dry. Build up the layers until you get a good base, a few coats sound do... Sanding between each coat, just to remove any build up or blobs. Then start the same process with your colour.
Try to blow the colour in, but dont go too far over as you'll end up getting to the point where the paint builds up too much at the edges.
Once you have done this, and applied lacquer if needed... Leave it for a good 14 days or so before polishing...
Use a sanding block with a rag on it, and a cutting compound to polish her up to flatten the paint back down...
You should start to see it matching quite well at this point.
There is easier ways but doing it properly always works well.
