[quote=”gtome” post=30092]Agreed, but I have to believe dry times are similar. But if will please the court, I would be more than happy to go get a quart of waterbased paint and a quart of solvent based and run a test if this needs to be beat to death. Fact is, water is slower than solvent.[/quote]
Man, you really don’t have any idea about what your talking about. You are just figuring out what clear basecoat does and your going to come out and make a statement like this.
You have never even used an automotive waterborne basecoat yet you know so much about them??? Really?
I would be more than happy to do this test with you.
[quote=”Ben” post=30105]I use water, and most of the time I don’t use blowers. Typically I let 3 minutes flash between coats…a little longer for some jobs depending on how I have things set up in the booth which affects the air movement. But nothing takes more than 5 minutes. I can honestly say, that in my opinion, water is faster than solvent most if not all of the time.
Not pushing products, but Sherwin Williams claims you can go from prime to shine in 40 minutes…it some instances that is definitely true.[/quote]
Do you toss a quick bake on inbetween coats ben, or just letting the base sit? If its the latter, you must have some pretty serious airflow in your booth… to get it to flash by itself. Your spraying autowave right?
I’m using Sherwin Williams AWX performance plus now. I use the flash setting on the booth between coats And before clear. Air flow is pretty good. The flash setting does increase booth temp. We’ve got everything set up as per the tech rep, and have made minor adjustments as needed.
I can’t wait to try water. Watching Jimmo’s vids with dupont that system would kill solvent for time. By the time I wait for the blending clear to flash water color would be done and waiting for clear.

Ya I’ve foiund the dupont water-line to be much faster then solvent for sure, the BASF one was hit and miss. Small jobs much quicker, larger jobs not so much. If you were in an ideal spraying envirnoment I think water will win everyday. Maybe his experience was in a poor spraying environment/climate where I can see maybe why he thinks that. On rainy days in my crappy cross-draft BASF waterborne was definately not faster then solvent.

Or he was using a waterbased paint designed for airbrush work instead of a waterborne paint designed for automotive refinishing :whistle:[quote=”gtome” post=30092] Fact is, water is slower than solvent.[/quote]
[quote=”gtome” post=30100]Ok, thats a good point, I dont know how to spray water. [/quote]
Can’t really add much to that as you’ve shot yourself right in the foot.
I’m not going to beat up on you as I don’t think that’s helpful, but just take a look around this place. There are plenty of experienced painters, and some very experienced ones. Some that have sprayed solvent for years and now spray water. If they say it is faster then you can take is as gospel. By all means go ahead and do your experiment, but whatever the outcome your results won’t change the minds of those of us that already know from experience.
I urge you to sit back and soak up the wealth of knowledge and experience that is on here. I’ve been at this job for 18 years now. Not long compared to some, but long enough to say I’ve got a good idea what I’m doing. I regularly learn new things on here though so I’m sure there’s plenty for you to pick up too 🙂
Well put Andy!
I’ve never used autoair peronally but a quick look at the website specifies normal application is with a regular spraygun and thinned out when airbrushing. I personally doubt the technology differs that much, but probably a better question for a chemist. At any rate its a tough sell generalizing solvent to be quicker then water.
Keep away from your adjacent panel, on lighter colors mostly silvers. The DBC500 like all wetbed products will darken the panel.
Spray wetbed 6″ from next panel. Your first coat of clear will overlap this by 3″ and clear entire panel with 2nd coat.
The clearer the clear the more depth and the darker the panel will be. This is especially true with waterborne wet beds.
Spray a med wet coat as you would with base.
Another benefit of a wet bed is the panel turns to a semi gloss shine the same as the base coat. It is much easier to see your blends.
Yeah I was pretty surprised the first time I sprayed it to find it was satin. Thought I did something wrong!
