Hey all please help... What is needed to properly sand a car? (89 firebird ).

i Would like to sand my car and prep for paint this up coming weekend, could anyone who has done this before please help me with this. It is my first time doing this but i am a fast learner and great with my hands so any help will be need and used any tips at all would be great.

Car is 89 firebird black and i am going to repaint the car black again just way to many scratches to paint over i think and want to sand the car myself but have paint by a pro.. Please help!!!!!????

 

I used 80 grit to bust through the clear to reach the paint. Then followed with 200 then 400. Epoxy primer (2 coats) 1 coat sealer 2 coats paint then 4 coats clear. Car turned out fine for a garage paint job. Just remember before you put sealer on, the car must be smooth as glass because any defects will show. Just pay attention to your flash times for best finish and gloss!

 

I would do 80 grit on a long board to show any potential low spots.
This will also give you sanding experience.
