Purely hypothetical at this point, please don't try to dissuade me as I'm not even ready to do anything yet. Simply curious:
Most roller paint job guides advocate thinning the paint and wetsanding after each coat. The paint thinning I understand, the wetsanding I'm not sure I get. Reason being, if you're wetsanding out the orange peel anyway, couldn't you just wetsand the final coat down to a mirror finish AFTER laying down enough paint to give you enough thickness? Or is there an added benefit of wetsanding the orange peel out of EACH coat that I'm not seeing? Thanks. |

Sounds logical to me, but the use of a roller on a nice car makes me shutter, lol.

Seen some mighty fine looking roller jobs. Plus, paying $100 for your paint job and having the ability to do any future bodywork or touch ups seamlessly is a big pro.

When you roll on paint you're puttinh it on much thicker than it would be if it was sprayed.
You're sanding each coat as it's dried, and the sanding helps it dry through even better. If you put on several coats one after another the first coats won't dry through if you load on another coat, it may never dry completely. You can get solvent popping when you put paint on too thick or too fast even with spray painting, you're just begging for the same results when rolling on several coats.

You could, but I think it would be more work, as you would be sanding out other imperfections that ocured (fish eyes and drops), and those will increase in size with each layer that is put over them.

That makes sense. I suppose it would be more work.

I've seen a lot of pictures of rolled paint jobs, but as i've said don't ever judge a paint job by pictures. With the right light and camera angle, any paint job ( even primer ) can look good.
I've seen 3 rolled on paint jobs with my own eyes, all 3 looked like crap up close, or distant.

Before they started using sprayguns in the 20s, all cars were painted this way, except with a brush. It's not exactly cutting edge technology. With the right paint, and techniques, a good job can be achieved this way. But so far i've never seen any roller paint jobs that were even remotely acceptable.
There's maybe almost as many ways to screw up a roller job as a spray job, and most people think they can shortcut the learning process.

Check out some boat sites, there are a lot of guys who swear by the "roll and tip" method using marine paints like Awlgrip, Petit, and Interlux.
