Homejob Panel Spraying Help

Ok guys, just welded on the rear quarter panel and acquired a new door and front gaurd.
All parts are on the car, and now it's time to spray.
Only problem is, I want the maximum quality out of a backyard job so I'd need some of your opinions and experiences with paint.
I'm using acrylic and have the basic elements such as a compressor and spray gun.
Can someone explain their way of spraying and prepping? <---more details in prep work as it is most important.
Oh- forgot to mention. The front and rear quarters are brand new, with no paint on them, whereas the door is already painted with chips and scratches. Whats the best way to bog? and what can I do so that all three panels are even (will the painted door give a different effect to the other panels?)
THANKS HEAPS!!

shouldn't u sand down the painted door before you paint? i think how it goes is that you should sand all the panels until u can 'feel' they are of the same texture and smoothness. Sanding it down with your hand gives u best results i was told.

so when u go to the paint take the fuel cover part to them and ask for an eye match of the paint
start sanding the door with the scratches etc down, is it deep scratches? so there no dent right, if theres no dents theres no need for bog work, so if the scratches are down to the metal you'll have to sand the whole panel down to metal to get an even finish with i'd say 800 sandpaper

well keep sanding evenly till u get rid of the scratches, after its all smooth and even remember to use a sanding block to get even effects, use 800 wet/dry, then u have to wipe it clean make sure its free from dust, oil, fingerprints etc cause u have to then apply undercoat, i hope u know how to mix the paint thinner, set the gun etc
after its been undercoated several times u have to sand that down to smoothness
then u can apply paint
then clear
then comes buffing/waxing etc
paintings a bitch
the preperation part that is

yeah for sure
Would paint stripper out of a tin make things easier? I've used this shit before, but only on bumpers, so not sure if it's strong enuf to attack the panel.
There are a few imperfections on it now (the door) like 3 golf ball dents (small) and very slight scratches.
So I'd have to go all the way down to the bone?

Shit no, don't use paint stripper. It'll be an awful bloody mess and will require repeat applications to get all the paint off. You can use a bit of bog or putty to fill scratches as long they aren't too deep. Home spray painting has been discussed a few times recently, with some good tips and approaches mentioned.

Cheers lumpy, was in the process of reefing out the tin and painbrush 
So in my situation, would i just bog over those lil imperfections and sand over - then paint over everyhthing?

Unless you are super confident you can shrink the dents out or feel like taking the whole lot back to bare metal that's what I'd do. Not the perfect solution, but bog/putty is made to patch srcatches and small imperfections, just not whole panels (as most people do!). Giving it a good sand until smooth and then a guide coat to show any high spots is a good idea.
99% of a good spray job is preparation. Don't rush it and you'll be OK.

Use a undercoat too - if you have it. A couple of coats of this, then sand lightly, will improve your finished gloss and smoothness no end.

hmmm......
yeah just thought if i could get away with NOT sanding the whole door down. What you reckon? Will it have a significant difference in the end result if i just sprayed over the top?

You slack prick !!!
You don't have to go back to bare metal, but if you don't get it smooth and even, your top-coat will look flatter on the door and thus pretty shitty. Also you'll need to degrease throughly in case the door was perviously waxed etc, and because it's old and probably coated in shit (that you can't see until you spray over it!!).
And you'll have adhesion problems if you don't sand and degrease - the new paint will peel off etc etc.
Good Luck - you now know why panels beaters charge the earth for what looks like a simple job

I have a new found respect for panel beaters. Now I know what I'm doing (main reason I bought my car was to learn), I'm going to get someone else to do it next time

and proud of it
Nah, was just wondering what will give the best results. Cuz i'm afraid (from previous experience) that if i do wack out the sand paper and all, I'll stuff up the door, and the end result will look even worse than if i just painted over the existing paint. 
So can i sand just certain areas ? (where there are scratches)
I was experimenting with bog yesterday (nasty smelling shit) and i'm afraid this stuff will stuff up things too. How would i apply and sand say, a golf ball dent on a door?

u need to knock the dent back out if it is deep and sand it back good.
dont sand patches...it will look crap, coz u will never match the surfaces.
and u will be very surprised how much sanding marks show up after painting. they are really obvious.

Now that would depend on how fine you are with removing said sanding marks now wouldn't it?

Any differences in surface texture on a panel will stick out like the testicles of a dog when you put the top coats on. Especially with Automotive coatings, since they are very high gloss and highlight any surface imperfections.

well thats what i am saying-
you need to really attack them and work them all out, otherwise they really will show up more than you think.
