I used to do the same until we started using the cheapest crap we could get. Problem solved. It barely works the first time. Now it goes straight to the trash.
[q[/quote] i’m glad it’s working out for you. When i first started the trainer told me to set the sata @ 25psi, it was going on too wet, took for ever for it to dry, or at least the last coat. Die backs were killing me. Then my rep who was also a trainer told me to up it to 29 psi. The difference was unbelievable.
It will sound high considering you probably were spraying solvent around 22-25 psi before. More importantly, don’t worry about how high the pressure sounds as long as the gun is doing its job, is all that matters. Now when the hot weather sets in & the humidity gets higher don’t hesitate to reduce to 30% for faster dry times.[/quote]
That’s funny. My trainer told me to spray at 20psi with sata. Which was probably more like 16 with my gauge. Ill definitely try the
30%. Thanks.So, after a week of spraying with higher pressure my work has looked better than ever. Not really sure if the pressure on the digital data’s is accurate because 29psi sounds like its much higher but, it is working.

I think you might be on to something with the air pressure lild. I barrowed my helpers digital 4000 today and noticed that 29psi on his gun sounded like 40 psi on my non digital. So I checked my guages to both of his digitals and found my gauges were reading 10psi higher. So when I thought I was spraying at 29 it was actually only 20, and my orientation coat was 10-12. After spraying a couple of cars with his gun they were flashing and covering so much faster, and laying down so smooth. I really cant believe that was it.
The 6659 clear really work well too. Its a lot easier to lay down than the 6100. Hopefully today wasn’t just a fluke cause I’m tired of losing sleep over this.Thanks again to all of you. Ill give an update in the next week or two. :cheers
We’ve been using the aquabase primer ( which I think is the same) on everything for two months now and I think it works pretty good.
It does ball up on the paper a little when dry blocking, so one of my helpers likes it and two dont . One thing I really like is that it doesn’t shrink up. I think that’s because you can’t abuse it without it mud cracking, so it forces them to let flash off.Ive always done two coats with about five minutes of flash between even when spraying solvent base with the same clear with no problems. Just tried a double coat because it was suggested at the training center.
Seems to take 3+ drop coat on most colors for me to get full coverage when checking with the sun gun. I always try to use the correct shade of sealer but this one was a two tone and I didn’t Want to re-seal it for the darker top color. It does seem that more coats of base= more pinch. My three stage jobs usually look like ass on the sides.
Also thought is ad the weather here has been mid to upper 70s with humidity usually below 20% which I’m sure is lower in the booth since I keep the booth around 85.
Well the red one came out ok. I just got a little pinch on that one. The one I did Friday though came out horrible. I ended up sanding and reclearing it. On this one the color was transparent so it took me five coats plus the orientation coat. I put the blower on it between every coat for about five minutes then double coated the clear as they suggested in the class. Ended up with 2.2 mils of clear. Gonna try a different clear on the next few. The only other clears they have here are the 6659 and 6800.
How long are you guys letting each coat of base flash?Thanks for all the help guys. I accually tried the temp gun on one a while back after noticing how cool the base was to the touch if you didnt flash it good.Didnt seem to make a difference. So today I tried putting lighter coats of base which isnt the way i was first instructed, and It seems to be working so far. It was usually worse with solid colors and three stages and it seemed like no mater how long it flashed they stayed a little tacky. I just finished a solid red one before I left so we’ll see how it looks in the morning. It didnt have that tackyness to it when I tacked it off this time.
OH… IM using sata 3000 & 4000 hvlp 1.3 for base and supernova 1.4 for clear. Ill put a mill guage on it tomarrow.
