Rattle can paint job vs spray gun paint job

(1/2) > >>

m_fumich:
Expense and color options aside, is rattle can paint or primer different than what I can get to shoot from a gravity fed spray rig? I once read in a forum somewhere that rattle can paint didn’t contain hardner. Can someone school me on the differences between these paints?

Could be true and that makes sense otherwise why is it not packaged that way for a real spray rig?

This is out of my league, but my neighbor growing up owned a body shop and I asked the same question once. I don’t remember the exact answer, but as I recall the real difference had something to do with the way the aerosol evaporated as it dried which basically rendered it chemically or molecularly inferior to gun applied paint.

This has been probably 20 years ago. Is it still accurate? Has rattle can paint evolved? Was it ever correct or total bullshit? I can’t say, but it might help you in searching for a good answer.

I will say this, I’ve never seen a car painted with a rattle can that looked good, but maybe I just haven’t been looking hard enough.

I once saw a forum post about painting a car with a roller. The paint went on thick and there was a TON of sanding to get it smooth but the finished product was great. As for painting cars with a rattle can, I know prep has a lot to do with the quality of the final result. So does the sanding after each stage. I’m tempted to take a piece of sheet metal and use the techniques I’ve seen in all the videos I’ve watched to see how good of a job I can do with rattle cans. Oh, I was also told that auto paint stores can put custom pain in rattle cans. I don’t know if that’s true or not.

They can, but it will be more expensive.
