Waterborne paint

Anyone using waterborne automotive paint for spraying a complete car or truck.

I am very interesting in trying it and would like to hear from others who have already done it.

Wonder about the brand of paint to use along with which clear coat.

I also want to use a 3 stage Turbine System to spray it with to help keep the over spray to a minimum.

Special thanks Jimbo

I've settled in with PPG's Envirobase and really like the matches. Hope to here how the turbine works and think it might be better in some instances then a regular air type gun for wateborne .. the air can be heated with that right?
The trick with waterborne is to get the first coat on wet without a run and then dust in subsequent dust/control coats..

Waterborne likes air movement (just a little) and non humid conditions,, here's a clip where the part is moved through the air and fans the part that is in a stand

Thanks for posting that video clip.

That was very helpful.

I am new to waterborne and I know that many would say just spray solvent based paint but I really think waterborne is the way of the future it's just that there is a learning curve to it just like anything else.

Just learning what paints others have tried with success is a major part of it.

I will be using a turbine 3 stage system and it does spray with warm air which seems to eliminate the fish eye problems also. I also like the fact that you car take it with you for small jobs and just plug it into any 110 outlet.

Most of guys who do mobile work use these units and swear by them.

I also like the fact that it really controls the over spray problems a lot better.

Thanks for the tip on the paint you are using. These are the kind of tips that are very valuable to someone learning about waterborne paint.

Thanks Jimbo

If the option is there you might want to reconsider and go with a regular paint. You don't need fans everywhere bouncing air and dust on the surface. Besides, auto body pollution only accounts for .05% of all pollution of the world. These lawmakers are just clueless on how to approach legislation in regards. If you want waterborne your gun should be stainless inside and approved for waterborne, you should have fans bouncing air off the car at angles, you should have other things like tack rags that are for waterborne. Some would even say waterborne approved paint sticks but that's getting a little nerdy. The main thing is sticking to one system. You can get away with it with normal paint but the technology of waterborne from brand to brand is still in it's infancy and they're not all compatible. Me personally, when they say better for the environment, it's usually worse for what it's intended for.

I did some airport avis jobs when envirobase first came out and it was junk. We're talking a silver metallic hitting the surface and changing colors as it dries. If I wanted a colorful rainbow I'd get a bag of skittles. I'll gladly pollute the environment with quality paint for as long as possible and these tree huggers can kiss my arse.

The "jump" from solvent to waterborne calls for no shortcuts in final prep...
There are a few painters east of the Mississippi putting up some waterborne vids. One to watch for would be Rich at satajet883's channel - YouTube

Not easy to tell everything in one post or video but you can learn a little here and a little there,,, take what helps leave the rest and then throw in some turbine experience when you can..

Thanks for posting that information and you are right!!!

There are no short cuts in prep and there is a learning curve with using a Turbine 3 stage system and also with the waterborne paints but I also think that sooner or later this is going to be the way painting will be done in the future.

I have read many posts by others who are using waterborne paint and I have met a few guys in person who are shooting waterborne paint and all of them had interesting comments on the pros and cons of making the transition from solvent based to water base paint.

One guy I met made the change because the shop he works in only works on high end cars like Ferraris and cars like that and he told me that all of those cars are shoot with waterborne paint right from the factory.

He told me the metallic s lay down flatter with waterborne then with solvent bases paint.

He also said sometimes they wait day's in between using the solvent based clear coat.

Thanks again Milo. Jimbo

be sure to get a good turbine system and gun otherwise you'll have to add too much reducer to get the clear to atomize. the old company I worked for had two, one good and one lame. The owner got the good one while I got the lame one. Tried his out and it was night and day...his atomized better AND had a bigger fan. In any case, turbine sprayers are pretty amazing and even the lame one was cool.

And just to demystify this stuff, check out this thread where I painted a fender using an aerosol sprayer and waterborne!

Compressor-less all aerosol repair review.

Here is an update on how it looks after sitting on the roof of the shop for a few years. So how's the all aerosol job holding up?
