Default water based paint

Hi there, I am looking for some advice. My 79 is bare and ready to start coming back to life. I would like to use a water based paint system. I want to paint in my garage and use a system that don't require a professional paint booth. Has anyone ever used Auto-air paints and if so what was the result. All advice/opinions would be greatly appreciated. Thanx in advance.

Default water paint

My understanding is it is not a water base but a paint carried by water. Either way it will mean that it will have to have the water evaporate to dry, and with out a professional booth with aditional air flow support it may be hard to get a clean job in a garage. Quick trying paints work best in a garage. But I am no expert and I am sure painters will chime in here.

I am sure that water based paints have come A long way since they were first introduced. The company that I work for had a couple of it's aircraft painted with A water based paint and within two years they were faded awful bad and had to be repainted.

you need to have fans blowing air over the paint to dry it. i think using water based requires a better booth than solvent based.

My shop has tried water based paints and I dont really care for them. I know its the way the industry is leaning but I will use the old reliable every time as long as I can.

You dont have your profile filled out. If you are close to Nashville TN you are more than welcome to come use my booth at night or on the weekends for free if it would help out.

Thanks and good luck!
Jake

You might try posting in the paint forum which is apparently not easy to find as there has to be a sticky at the top of of the General forum which links you to a link which takes you here:

Thanx Jake, I live in northern Colorado so i don't see me getting out your way. That a very cool offer though. I was looking for anyone who may have tried this water based paint in the past. I will be setting up a booth with lots of air movement to help with the drying process and the dust issues. I would still like to see any and and all advice. If I have to i guess I will blaze the trail and see out it comes out. Thanx Dave

I've studied waterborne paint systems for the last several months now because we have been contemplating moving to a waterborne system to a get ahead of EPA regulations. All of the OEM's use it with out exception. It's the only way that they could meet EPA requirements. The main advantage is low VOC's the only change to the booth environment is you must have direct air flow over the painted surface for it to be able to flash. And that can be done with a hand held or a rack air dryer. If a painter is trained properly with waterborne there is no reason why a paint job can't be just as good or better than a solvent born system, waterborne actually has better color matching than solvent born systems. But I think you need to have pretty good experience in automotive paint systems first, it's not for inexperienced painters.

I attended a water based paint demonstration a few months ago. Very impressive stuff, easy to correct mistakes, much easier to blend the color than conventional urethane based products currently in use. You will need to have a drier set-up to cure the water based base coat (color) which could be a problem in terms of $ as the one I saw in the demo was not cheap. The other problem is that while there are water based base coat systems on the market, they currently require urethane based clear/top coats in which case you would be better off just going with a conventional urethane based system. Good luck!!

We plan having a couple of air dryers like this on a rack 2 of these is more than sufficient for 2 or 3 panels.
And yes it's true that there is not yet a waterborne clear but removing 85% of the solvents from the base coat helps a lot in lowering VOC's. I've been told that waterborne clear is not far off. But in the Great Lakes region they are going to require waterborne in the next couple of years it's inevitable and it's already required in So Cal and in some northern states.

The demo that I attended was in Austin. While the ease of use was the main focus about the product, VOC and future environmental restrictions were also discussed at length. There was quite a bit of discussion about the required use of water based products in California. Been used there for many years. The supplier also commented that waterborne clear would be on the market soon. I was very impressed and have no doubt that waterborne will be required at some point in all metro areas. I see it as a positive step.
