I never understood why people primer their entire car. I thought it was for areas that have been repaired and it's so the paint can stick to that area better?

Well yes its for the paint to stick better, and you definately want to primer the entire car. In the older days, it kinda sealed the metal. As well metal and fiber glass is not an even surface, there are swirls and scratches and stuff. The primer is a surface that can be sanded, and your paint job will turn out nicer. Im sure there are a few more reasons for it too. Perhaphs someone could ad to it.

You have to understand there are different kinds of primers not all primers are for the entire car some are for spot repairs , these are primer surfacers they are sandable and fill small imperfections in bodywork they generally aren't used to prime a whole car (although some people use them improperly) some primer surfacers are not water resistant and will actually absorb water (not a good thing).. Thats where a primer sealer comes in these are the primers that you would use to seal the paint and body work left on the car down and provide a smooth surface after the primer surfacer is blocked out and for the paint to adhere to ... the problem is you must use matched Automotive type products which alot of the spray bomb stuff is not , the only thing I would use a spray bomb for would be to do a temp repair with it and use automotive spray bomb type paint over it right away to prevent rust , again only as a temporary repair ..if you need body work I would save up and get a repair done with the proper paints and primers ...

This is probably a dumb question, but is there a rattle can primer that you can use to prime your whole car? I'd like to prime my whole car when the body work is done, but I dont wanna pay someone else to do it. I realize that it would take a bunch of cans, but I don't see it costing more than paying someone else to prime it. And I dont have a garage, or a compressor.

project '86..while alot of guys will sit back and tell you how bad some things are and how they would never do this or do that, alot do it anyway. So, the answer to your question is yes, you could infact primer your entire car with a spray can(not sure wth a spray bomb is, must be regional slang?), I would be willing to bet that thousands of people worldwide do it every year. Obviously it will not give you the perfect job but it will work if you follow the directions and do it right. Technology is much better than it used to be and the nozzles on spray cans are better. I know a guy who did exactly what you are asking and his car has won best paint in quite a few car shows. Hell I primered a '67 International pickup with a wagner power painter and the paint job still looks good to this day..I did it in 1982!

Thanks for the info Aero.

And just to fill ya in, where I'm from a Spray bomb is the same as a Rattle can. Not sure if it differs anywhere else.

But anyways, I was just wondering because I'm repainting my car, and I was wondering if the paint would turn out better if I sprayed my whole car in primer before I sent it to paint, or if I should just sand the whole car. My buddy said I should just sand it, but I want the best results that I can get for the amount of money I can put into it. I don't have a lot of money to throw into the paint, but I dont want to half-@$$ it and have it look like $h!t in a year or two. And to clarify, my car is red, and I'm repainting it red, but not the same shade. Probably a little more deep of a red.

Canadian tire buddy! Ive done it on three cars, no problems yet. However, if you find yourself doing this alot, invest in a compressor and paint gun. Between my freind, my brother, and myself, we have about 10 cars and we decide once in a while they need a paint job. A BIG can of primer for ur spray gun, and some varsol is alot cheaper than 6-8 cans of aerosol. Just do it outside, and if you must do it inside, use ventilation and a mask! If that stuff gets in your lungs its there for life.

As for the quality, the aerosol primer you buy from canadian tire has a very very very fine spray. Meaning, the way they mixed it, turns out beautiful, and as long as you spray very little at a time and wait for it to dry between coats (ie: no runs), it will turn out nice.You may even get away without sanding it. Havent been able to get paint to come out as nice as it does out of the spray cans. Good Luck

unfortunately, spray bombs contain about 4oz of paint, but you have to pay for the can and propellant. The spray can also puts on the paint super thin compared to a spray gun, so you virtually can't use it as a primer surfacer. Something like .5 vs 20 ( I forget the unit of measurement here, but I remember that was roughly the comparison). So you'd need like 30 cans to do a whole car, if you wanted to lay the same amount of paint on it.
This is kinda why it's next to impossible to get spray can paint to "run", it's just not enough volume of fluid that you're spraying. I mean, you gotta be pretty useless to get runny spray can paint, whereas with a gun, it's a fine art to avoid it eh?


spray cans are also single stage, ie no hardener, so it's going to be considerably less durable, just due to it's nature.
If you find an automotive paint shop in town, ask them if they can fill a spray can for you. They can put anything into a spray can (or many) and sell it to you. Get it mixed with hardener and RUN home and paint.

Look for a link to a forum on mopars, where a guy used tremclad enamel on his car. Using a fine roller, and thinning the paint out like crazy, so it went on smooth. No primer used either. Tons of coats, and wetsanding, but came out damn nice. I was toying with this idea, but the types of curves on our cars would probably make it impossible.

I saw that write-up, it's on moparts.com, it was 69chargeryeehaa that started it. I thought about that too, but thought naa. The time that it took a few of the guys to do this, it would take me a forever. I couldn't imagine doing this cause rollin it on then wet sanding, rollin it on then wet sanding, rollin it on then wet sanding over & over & over again would get old. I know myself I would get burnt out on doin it. I think they said it needed like 7-9 coats.

Yea, but if you think about it, to do a "proper" sprayed paint, you're going to do the primer 3-4+ times, then base and clear. You're going to be re-sanding that a lot as well.
Effort is more, that's not really debateable. I think i'd do it on a mid '80s chev truck say. These cars just have so many areas that I think would be impossible to roller paint... jambs? mirrors? nose? spoiler attachment? etc

86-Iroc-Z

No, I agree with ya 100%, but I would just burnt out on the rolling part.
