I have a steel sectional, overhead garage door that will not hold a coat of paint. It peels and flakes off. How do I get the paint to stay on my door?

You have to use primer, probably 2 coats or more. It is going to have to be a really good primer if you want the paint to stick.
Clean the surface and remove old paint. Then paint with a primer for steel. Then paint it with what you want.
Oil is usually the cause of this. Make sure it is clean, a light scoring – sanding, prime with a metal primer, and paint. or have professional paint it with a warranty!
Sand the whole door with 400 grit sandpaper. This will put small scratches in it that the paint will adhere to. After sanding wipe the whole door down with a paint thinner like naphtha. This will remove any oils that might give you a problem. I would use a good paint like rust-oleum afterwords.
Its all in the PREP work!
Clean, sand, lean again!
use good paint!!
If the door has been previously painted, give it a light sanding to roughen the surface. If the door is plain galvanized steel, you need a proper metal primer paint as an undercoat first. Go to a paint shop or a hardware store and tell the resident paint expert what you have and what you want to do.
For sectional steel doors, clean the door power wash , or srub brush. Shand door to remove all shene on the door 120 grit paper, preferd method plam vibrating sander, wipe door down with paint tinner or minarial spirts. Apply cote of ext. flat oil base primmer. Paint door two coats ext oil base paint. Remember preperation is worth the effort.
