I have a 66 impala and I want to paint it a black suede/primer.
I am really poor so Im going to rattle can it.
can someone tell me the best rattle can paint for cars,
and can I paint over the existing paint without primer or
should I primer first.
I know some of you will tell me that I'm an idiot for rattle can
painting my car but the car has a lot of bondo and I'm just
trying to build a decent looking low buck custom.
thanks,

The paint dosn't matter as much as the prep work to make it stick.
Sand it real well and cheap paint should work ok.

I you have access to an air compressor you can paint it with John Deere blitz black around here a gallon goes for $24.00. I have even heard of somebody putting it on with a paint roller.

I don't know what brand you are planning on using, but if it's anything decent, you'll be paying around 4 bucks a can, and will take a lot of cans. It's worth considering, I think, because it may end up costing as much as a better topcoat. For the "suede" look, epoxy primer will certainly hold up better, protect the metal better, and it won't fade as fast.

If you are bound and determined, the best method is to mask off small sections, and do one bit at a time. Otherwise, if you try to do too large of an area, it will dry too fast, and you won't get a solid wet coat. Then it would look tiger-striped and goofy.

I'm with unioncreek on the JD blitz black. By the time you buy enough rattle cans of paint to cover an Impala, probably about twenty, it would end up being a lot cheaper to rent a compressor and gun and throw the blitz black on there. And that JD blitz black is some awesome stuff for the price. It will last a lot longer than any rattlecan stuff. But either way, its all in the prep job you do.
Another thing I like about JD blitz black is it also comes in rattle cans in the same formulation as the spry gun stuff, so touching up repair areas later is no problem.
And just like other paints, if you have any bare steel showing, you'll want to use JD's primer too. But it sticks fine to degreased and roughed up old paint.
