Advice on prep (sanding and priming and masking) before painting -- Help appreciated
Has anyone ever done their own sanding and priming before taking their car to be painted at a shop?
Is it possible to damage my car's body with sandpaper?
What grit sandpaper should I use to ensure no damage is done?
How will I know I've sanded far enough?
Does sanding to bare metal offer benefits?
Is it possible to sand past bare metal and permanently **** up?
If I'm changing color, do I need to sand down to bare metal?
If I sand to bare metal should I use a dual action air sander or a hand sander? I mean is it possible that using a machine sander will take me down too far?
For masking, is a single layer of automotive painter's tape enough for small areas and what should I use to mask larger areas, plastic trash bags?
Is applying your own primer a simple process? I mean: Is there a chance to **** up and have to restart?
Thanks for anyone with the experience.
first time is a learning process.

How will I know I have sanded far enough down? Do you have any pictures? This will be my first time doing anything like this and I severely don't want to mess up :)
sanding,preping,and masking are painstaking,time consuming tasks.it sounds like you are seeking a factory quality paint job.if you want perfection you are gonna have to pay pay pay pay pay.is the shop cool with you masking the car?.alot of the tape is applied directionally so it can be removed when the paint has set just enough to adhere but not lift.all trim that can be removed should be removed,all lights,grills,bumpers,mirrors,locks,outside window scrapers,running lights and side markers.the less you mask the better the result.sand flat surfaces with da sander and all contours by hand,if you go to bare metal in any area youve got to touch up with compatible primer,i wont get into etching.any area that dosent get sanded or at least cleaned to remove all traces of anything other than clean paint will be prone to peeling.be really carful with the high power spray washes.i just talked myself out of ever painting another car.you can totally tell when you are through the clear coat by wiping the area with a damp towel.oils of any kind are your enemies,you have to have really clean air for your sander,wear long sleeve shirts and dont lean on the sanded pourus paint when your sweating,thats really tough to remove completely.if you get through it you will have a really sano looking ride. bones
