It depends on the condition and colour of the paint on your wall. If it's all scuffed-up in places, you probably want to prime those spots to make it more even (after you've ripped/peeled off the pieces that are sticking up of course).
Also, if you're painting a light colour on top of a dark colour, it might be a good idea to put a layer of white primer in the middle.
Primer coats are most commonly used over new drywall, over any repairs of patchwork, over oils paint (use a good quality oil primer) when you want to change to a latex or acrylic top coat or when you are changing a colour significantly enough to warrant it.
As in when you are covering a very dark colour with a very pale one or when you are looking for a saturated colour for your finish... a red primer will make a deep red top coat easier to obtain with fewer coats.
Yes. you will also want to clean it with something like denatured alcohol first.
A good primer is essential as it creates a base for the finish paint to adhere to. Many paints may not be compatible with others, primer will deal with most disparities.
Sandstone fireplaces can certainly be updated with a lick of paint. Before painting, the fire surround should be thoroughly cleaned and allowed to dry. A primer should then be applied. Once the primer has dried, apply your chosen paint and allow to dry.
Yes, you can if you are sure you need to.

I would sand it down with sand paper then paint with primer. After that apply a outdoor paint. Prep work should be smooth If you really want it to be nice hit the primer with a light sandpaper after the primer coat.
Rustoleum makes a metal primer specifically for this purpose. Then, apply their paint over the top. Black looks especially good on wrought iron.
The benefits of primer is to solve common painting problems including stains on walls, moisture damage, old painted surfaces, odours, colour changes, and new exterior woods. Only two coats of primer should apply on the wall before painting is to be done. It is usually acceptable to use one coat of primer.
Because it will avoid problems withold oil-based paint (you ABSOLUTELY need a primer over an oil-based paint before painting with water-based/acrylic pain)patches made of different material (patches of plaster for example) that would react differently from other parts of the wallbare surfaces (new walls) which won't give good adherencecolour changes (if painting over walls of different colours, the result will look different with the first layer(s) of paint. The primer can help)
a primer is liquid you apply before painting , to help the paint stick to the surface that you are planning to paint.
You should have a paint spray gun that is designed for painting cars and vehicles. You should also buy the proper paint for cars. Green or red are good colors for a farm tractor. If you have rusty areas on the tractor, you will need to sand them off before you paint it.

If you are talking about what you should put on your eye lids before putting on mascara i would recommend eye primer. Eye primer will help the eyeshadow stick and stay all day. Then apply whatever eyeshadow :)
Masonite can be painted, but it needs to be sealed first. Sand the siding with 80-grit sandpaper or a sanding block, but do not scrape the siding, as it can dislodge chunks of the siding. Apply a layer of primer before painting.
Primer makeup is sometimes applied before foundation. Smashbox offers several primers (including Photo Finish Primer, Photo Finish Color Correcting Primer, Anti-Shine Primer, Photo Finish Lid Primer, and Photo Finish Foundation Primer Light) which may be applied the Smashbox foundation.
Make sure that it is clean and deglossed, patch any holes and cracks, then apply any texturing if needed. If there were many repairs, prime the surface with the proper primer. Stain block primers will cover water damage while a regular latex primer will suffice for a wall that is in otherwise good repair.
Shadow base would go on first. If you are using a shadow base, you should not need an eyeshadow primer. They are basically the same product. The only exception I can think of is if you are using the MAC spray primer. If that is the case, you would put on your shadow base, spray the primer on your shadow brush, put the shadow on your brush & apply.
