Steps to interior painting

so I looked through some threads and there was a lot of helpful but sporatic information. I'm surprised there isn't a sticky at the top giving you the step by step on how to repaint your interior. I'm a total beginner at this, so can someone please help by listing the steps you would take to repaint your interior (dash, parts of door, ceiling), what type of products you need, where to get the products, and about how long it would take.

These are the steps I got so far:
1)remove the pieces you want to paint if possible or cover the exposed areas that you dont want to paint with newspaper (windows, door handles, lettering, etc..)
2)sand them down
3)wash them with soap
4)use some kind of primer paint
5)paint multiple coats using some sort of specific paint (spray? brush?)
6)let dry
7)reinstall (if necessary)

Am i missing anything? what stuff do I need and where does everyone recommend getting them?

2) Depends on what your painting with , some products dont require sanding and I would never sand before I clean so as I dont work contaments into the vinyl making it tougher to clean.(my opinion)
4)Depends on what your painting with , some vinyl coatings do not require primer before application for example SEM vinyl dye. It actually softens the surface of the vinyl (hard or soft pliable) and bleeds into it. When it hardens it has become a permanent part of your vinyl.
5) In theory you could paint the vinyl with any kind of paint you want to however different coatings adhere differently and some work better than others. Exterior auto paints(aeresols) can be applied to hard vinyls but is risky on pliable softer vinyls(cracks and peels). I know acyrlic laquer (aeresol)will adhere to soft and hard vinyls but if you clear coat it will not have much elasticity. Theres lots of coatings that will work great and alot of folks in here can let you know what they use and how it works for them. Most products will be aeresol type products but someone in here might know a good brush painting method.
I hope you find all the information you are looking for and good luck with your future projects :)

My dash trim is all plastic, and removeable. I took it all out, and I may or may not have washed before sanding, I think I did on some but not on others... But let me recommend that you wet sand with a fine sand paper. I used dry, coarse paper on one of my pieces and it left heavy scratches (good thing I had that as a test piece). DEFINITELY go to a junk yard and find some test pieces to paint. If you cant find the exact pieces that fit your car, then find something of the same material and finish, so that you can get the feel of it before you paint your own interior. Now that I thnk about it, I believe I washed my pieces, then wet sanded them, then I rinsed them in water, let dry, then applied paint. For me it was difficult to get a perfect FINAL layer of paint, so I decided to wet sand after I had already applied a few coats. That helped a LOT. It got the finish very nice and smooth, then I applied one final coat and the piece came out BEAUTIFUL! I personally used Engine paint. I dont remember the brand, but it is the "DYNO TESTED" engine paint. It was heat resistant up to 500 degrees, plus it was made for engines so I figured it was strong. Its holding up very well. I made a minor scratch in it within the first 48 hours of it drying.. ( i was dusting it off with a cloth to make it shiny, and gave a minor scratch) so I recommend letting it dry a good 48 hours before you touch it. Since then it has been in my car (center console) and has had things dropped on it, slid on it, etc, and no new scratches, so I definitely recommend the Dyno Tested engine paint. (I decided to check what kind of paint it was, and it is Dupli Color High Heat)... very good paint. Look at the pictures of my car in the URL in my signature to see the paint job I did on my dash. Any imperfections in it, I blame all on myself for being too impatient to wait to see it installed. (you cant really see any of the imperfections in my pictures though... why would I take pics of the imperfections? lol)... so take your time, and remember that you are going to be looking at it for a very long time after you finish, as well as all the people you show it off to, and you dont want stupid mistakes to make it look bad, so take your time! Thats the most important thing I can tell you.

Sounds like you already got a good idea of what your doing. Dont take any offence but engine paint isnt the greatest stuff to use on vinyl , engine paints (aeresols) have alot of extra hardeners in it and while the top coat may be dry the lowwer coats may still be tacky after an hour , do not press your fingers into the vinyl while installing it cus those hardeners can soften the plastic and permanently warp it. Dyes and interior vinyl coatings dry very fast so you can add layers quickly and is dry to the touch after 30-60 minutes.Cool car! I use 1000 gritt sandpaper when I resort to sanding it is more than coarse enough to hold the dyes and paints and this way doing a dry sand isnt gonna hurt it. If you need coarser star with 320 and work your way up , vinyl is alot easier to smooth out with fine sand paper than coarse. 320 is a finishing gritt I use for wetsanding primer before a enamel base coat application but thats old fashioned exterior painting. I use 400+ gritt to finish old style laquer base coats too. Have fun rick keep us posted.
