Spraypainting?

Ok, mostly due to cost and time I'm considering spray painting my 93yj, at the moment it has the original coat of paint (a teal ish color) and the previous owners failed attempt at spray panting it black.

I'm pretty sure my dad has the stuff if I had the time to paint it correctly, but I am thinking that I might just sand it down and spray paint it.

Right now it has spots that have no paint because I ground off any rust bubbles, and it has blotchy black spots of spray paint.

What are the problems with spray painting a vehicle

With any paint job the more time you put in to prep work the better the final job. I am fine with rattle cans, many guys are not. Rattle can paint will not last like actual auto paint, but it is cheap and can be done without special tools. Spend a couple bucks and get one of those plastic spray handle things. Saves a lot of hand cramping.

Depending on where you live you might look for an automotive paint store. You can buy the correct paint, thinners and primers. And they will usually give you tips on how to do the best job. Then rent an airless spray gun or buy a Wagner from Lowes. It might not be the best but it will last longer than spray cans and you can color sand it to a pretty good finish. It is really all in how much labor your willing to put into it.

Good idea, I'll have to see if there is a paint place around so I can compare prices better.

I did daughters jeep last year with rattle cans of enamel paint and love how it turned out. Thread here: White to Blue rattle can paint job

Best info I can give you is to prep WELL, over prep, and tape till you can't stand to tape off anything else, then tape off some more and make sure you have clean tape edges. I did have to do some "spot" painting with a brush and the enamel sprayed into a butter dish for the tiny edges that showed up in a few spots when I pulled the tape. It still is shiny and nice a year later, no fading, but I let the enamel bake on in the hot sun. Same deal we do with tractors.

Well if you really want to spray paint it then sand it with 120 untill its even, you dont need to go to bare metal unless its really bad or there is rust. Use a can with a good head, I found Krylon Dual to be my favorite. It comes out pretty good too. If you want tips on how to do thing right then the paint section on the 67-72 Chevy forum is a great resource with a lot of people that can help with your painting goals.

120 grit is WAY to coarse to be spraying over with an aerosol. Minimum 400 dry or 600 wet.

Actually you want to use 220-320 grit sandpaper.
120 is way to coarse and will leave scratches visable after painting.
400-600 is too fine unless you spend a lot of time wet sanding.
For an Enamel or Eurathane paint job I generally use a DA sander with 220-320 and hand sand edges and places where da wont reach with 320 then use a Scotchbrite pad over the entire vehicle to insure everything has been sanded. Rent or borrow a decent air compressor and use a regular spray gun for the best results. A good gun can be purchased cheap @ HF for $20-30.
If you are going to spent $150 -200 or more for paint you may as well spend a little more and do it right.

400 dry or 600 wet is just fine for sanding for rattle can. I finish everything in 400 dry. Minimal shrink back. 220 or 320 on a DA is fine for prepping factory E- coat panels but not primed areas.

You say 120 is way to coarse and will leave scratches? I ask because my experience comes from using in on metal. I'm staring at it now and the paint looks even to me.

The OP was referring to repainting a bad rattle can job. I have been painting cars professionally for a long time and have been using a da with 220-320 since the first car I painted in 1972 never a problem. That is was I was taught in auto body school. 400-600 will work but unless you spend a whole lot of time doing it it will be more likely to peel and bubble. Why would you want to paint a car with a spray can anyway? Unless you are using a flat paint you will have blotches not to mention crippled fingers from using a spray can. You can paint a car in les than an hour with a spray gun it would take the better part of a day with a spray can.

If you are considering a rattle can paint job, you aren't going to get show car quality. Lets be realistic here. There is no reason to go to 400 if you are just going to rattle can it. Sure it can be done and you can get better results, but probably more effort than its worth for a paint job that is going to last 3 or 4 years.
