Do any of you have experience with the water based paint? I am asking because I heard in Cali June or July of 2008, paint sold has to be water based as opposed to urethane based. Would I still be able to paint in my garage and can you touch up stuff on an already painted car? Basically what is different about these paints? I have some experience painting with regular paints. If you have helpful insight, please list pros and cons with experiences using water based paints.

Don't know much about the new stuff and new regs you're referring to. I DO know I don't care much for Auto Air waterbased paint for airbrushing.

We use Standox water-borne at our shop, doing collision repair. The only part that is actually water based is the basecoat. And yes, you can touch up stuff. It works pretty much like the traditional system, except for a few things.

1) you shoot it totally different, it takes far less time to base out the car, and you can lay it on wet wet. 2) you can help the base dry by using a blower on a stand. We use SATA dry-jet system so it is filtered air being blow on the surface3) you must use a regular solvent based wax and grease remover like before, but you must then use a water specific wax and grease remover, that smells like straight rubbing alcohol. And you cannot touch the surface with your hands after that step.4) forget sanding imperfections out of your base. That sh*t never seems to dry all the way and if you try to and it like the old stuff, you will probably tear it.

All that said, I really like it, it's funny to mix up your color and pour water into it to thin it. But since most systems are very new, the color match is iffy. The metallics do weird things, and blacks are hard to get right, so we keep some old style black around for those jobs.

the point of the waterborne was because of people painting in their garages. The VOC levels were too high, and too much solvent was going up into the air.

It will still paint somewhat similar. But airflow is going to be key. With more airflow its going to flash faster, but with airflow comes humidity. If there is moisture in the air, it wont flash.

And its not entirely waterbased. There is still solvents in it, its just a smaller amount. Ive sprayed the Dupont, RM, and PPG waterbornes. Its going to be a little harder to spray in a garage atmosphere, because you wont be able to wet the floor, and your going to need way more airflow. Thats where the sata blowers come in handy.

With backyarders, if theres one thing I have learned....its when theres a will, theres a way. Everyone will figure out their own way of making it work effectively.
