Talk to the place you get your paint from - different types of paint need different types of primer. They'll be able to also help you with your supplies you need (Putty, etc...).
As for sanding - it's best to be taught by someone. All the little things add up - like not sanding with your finger tips since that leaves uneven areas - always use your palms.
All those little things - they need to be taught.
I've seen guys who paint for 10-15 years and still learn new stuff. |

| if you're just planning on painting the winter beater, start with a 400 grit paper, sand all the rough stuff, and then use a 800 grit....primer....800 grit again...then paint. |

The paint shops sell a special cloth that you rub all over your car so that you don't get any dirt/dust/lint trapped into the paint. Buy one of those (Don't let it touch the ground), and rub it over any area you want to paint before painting/priming.
Since you're painting it in the garage, you'll obviously get some imperfections in the paint. But little things like this, and wetting the garage floor can go a long way. |

| You're talking about tack cloth. Wipe the car down with that between every coat of primer/paint. You can get it at CT. |

Yeah - that's the name. I just know where it is in the shop I go to.
Also - if you're repairing a bumper remember to add some flex agent in (if you want a good job) so that it does crack.
Because the bumper isn't metal, it can shift itself, or when leaned on, etc.... If you don't use a flex agent it'll crack in the paint.
And anothor tip - make sure that the rubber around your windsheild is raised or else the paint will peel between the edge of the rubber and the roof. I use a piece of twine under the rubber all the way around, that way the paint gets under the rubber and won't crack. |

| Another good idea if you are doing any flexible plastic parts is to use an adhesion promoter rather than primer. It will help the paint stick better to plastic parts. |
