The PPG Envirobase is almost exactly the same as the Nexa Autocolor. I work with Nexa since the day i started painting. Here in the Netherlands almost every company is painting with waterbased paint. My company started in 1991 with the first waterbase. So for me i dont know really better and im painting for about 5 or 6 years now. I did some work with solvent based paints a couple of times. For me it seems not bad. I think solvent needs more coats to cover and is more difficult to spray. Especially the last coat (dont know how to say in english, i think it is orientation coat? )is harder to spray nice and even and not ”cloudy”. But that is only my opinion.
He guys,
I had to paint this color today. Our customer complained by the Renault dealer that the bumpers didnt match the rest of the car. The car was new from factory. He won the case and came to us for the repair. And he was right, the bumpers were to light/trantsparent in comparison with the rest of the car. To bad i didnt take a picture to show u guys.At my shop we work with Nexa autoclor/ PPG Envirobase. I used my photospectrometer (don’t know if this is the right translation 😉 ) and i picked the best one that came out. It was a C(x2) wich means it is two times cleaner then the No.1 color. I sprayed some cards wich were not to bad. If i could blend the panels i would use the color right away. So we did a little adjustment to the transparent layer. A bit more orange pearl/metallic (fireside copper xr-16). Sprayed a card again with the right amounts of transparent coats and i was good to go.
Tommorow the bumpers will be installed and i will take some pictures to show u guys.
This is the base color, its a pink metallic.

My colleague painting the transparent layer. 3 coats with a 30 cm distance at a slow speed.
The difference between coats
Almost there 😉
So its a pretty weird color, but it worked out fine eventually.
Goodluck everybody in the future;)EDIT:
This is the result. In the picture it may seem the color is a bit off, but in reality it was near perfect.
He guys! Thanks for your replys, again!
Well it seems the problem i have has something to do with the air velocity in the spraybooth. (don’t know if im using the correct english words)
Another technical guy from PPG came by to take a look at the problem. This guy knows really much about paint and also about spray booths. He did some measurements and came up with this problem.So im gonna try to explain it to you guys.
If i spray for example clearcoat (or basecoat, it doesn’t really matter) i apply one or more coats. So when i lay down my first coat, and wait to put on my next coat, this is what happens:Because there is a to high air velocity in my booth, the top of the coat will close or dry to fast. what happens next is there are still some solvents and other chemicals under it, that cant get out anymore. So then i apply my next coat and let it bake. the thing is, i can let it bake till christmas, it will never get completly hard.
So imagine what happens if i put a few coats of base, wich got the same problem and the 2 coats of clear, it will stay soft and the solvents cant get out, so it never gets hard.
To test this i painted an old hood outside my booth. i let it dry for a while and after some hours i wanted to give it some heat, so i put an infrared dryer on it. And….. it was hard :exci
Ofcourse there need to be done some more tests, but next week some technical guys come over to fix the booth and we will see what happens next!
Anyway thanks for all your input and help!
And lets hope i can paint like glass again! :whistle:Thanks for your replys guys!
This morning is was checking the test panel i painted saturday.
At all 3 parts i did the fingerprint test again. It seemed the panel was hard.
However, when i put my nail in it, it leaves a mark.
This was only on the first 2 parts were i applied the basecoat.
The die back ( i guess i should call it like that) or the lack of gloss only happened on the first 2 parts of the hood, and not at the the 3 part were i only applied an new layer of clear.
The first part was the worst, 2nd part also but less.So my technical guy from PPG came over to take a look.
He agreeded with the dye back and stuff. He also checked the booths but everything seems ok.
He changed the flash off time of the booth, so it is about 2 minutes longer and the temp. will go up bit higher.
So we cant tell yet what it is, but it seems its in the base.About the clear that im using. Its the HS+ express clearcoat. P190-6659.
But we checked it and everything seems fine, from start(mixing) to finish(aplly)
I know the bake time is at metal temp, so we are sure that isnt the problem.
So this clear is made for speed, and the fastest from NexaAnother thing i forgot to tell you guys, i painted another testpanel on saturday.
This was a 2k uni solid color. the P471 line.
This one doesnt die back and is still shiny and hardness is good.
i did the fingerprint test, and it was much harder then the other waterborne panel.So today i painted a volvo, and it seems i did a pretty good job, but we’ll see tomorrow morning 😉
Im going to paint some more testpanels to figure out whats best.So, any suggestions or comments, please let me know!
Thanks guys!It looks nice!
[quote=”smooth” post=28709][quote=”Rel” post=28706][quote=”smooth” post=28690]I use a 4000rp for clear. I was initially using a 1.3 and shot many different clears with it. I found it too slow for my style.wouldnt want to try a 1.2. I am now using a 1.4 but still not the fastest gun out there, if it were me i would use the 1.3, Nason clears are on the skinny side.[/quote]
Smooth, if you are painting Nexa Clearcoats, like the 6659 express clearcoat, How do you apply them with a 1.4? Really fast and close to the object? And with a 1.3?[/quote]
I cannot get the 6659 because i live in Canada, im using the 6759 (basically the same clear). Was using a 1.3 but found it too slow like previously mentioned. Using a 1.4 now close and fast seems to do the trick. Im really liking the 6800 speed clear have you tryed it?[/quote]
I think i cant get that clear around here. I use the 6659 express clear, 6690 hs clear, 6512 ceramic clear, 1061 matt clear. all with my 4000 RP 1.2. it is a bit slow ( 2 normal/full coats). I think i’m going to try to spray with my GTI PRO 1.3 T110. But i have some issues with spraying my first layer of clear thin and smooth.. any suggestions on that?

[quote=”jasonsdream” post=28475]is anyone using a rp 4000/1.2 for clearing,and if so,tell me about it.i’m using the 1.3 now[/quote]
I recently started to use the 4000 rp/1.2 for clear. It is a bit slow. I used a 3000 rp 1.3 before. It depends on what clear you are using. If i use a 1.3 i have to apply 1 smooth light/medium coat, and 1 normal/full coat. if i use the 1.2 i have to apply 2 normal/full coats. With the 1.3 i spray a lot faster then a 1.2.
I work witn Nexa AUTOCOLOR btw.
[quote=”smooth” post=28649]Hows the Nexa been working for you???[/quote]
So far, most of the products are good/great. The new Eco+ primer is really good. And im a fan of the aquabase plus. Its a huge advantage that you don’t have to wait until your coats are completly dry to put on the next coat of base!
[quote=”Jayson M” post=28644]Yeah thats the place :p She came to Canada after WWII when she married a Canadian (my father in law).
I used it back in the 90’s when it was called ICI,very good product,can’t say the same thing about delfleet,not a fan .Once again welcome to the site, :cheers[/quote]Great story!
Yes back then it was called ICI. Our shop was a pilot company, the aquabase products were introduced at our shop for the first time. So there is a lot of history. The delfleet isn’t my favourite. But i almost never have to use it.
[quote=”protek9543″ post=28639]Hey Rel I work with Nexa and Delfleet. I’m a Technical Specialist in South Florida.[/quote]
Oke great!
So you work for PPG then i guess?
I’m a big fan of the new Eco+ Primer!He,
i started with sanding and stuff like that when i was 13. In my holidays and free days from school i worked at the bodyshop. When i was 16 i started with automotive college and got my ”papers” ( dont know what the correct word is) and become 2nd car painter, then 1st car painter, and i recently did exames for management stuff.
how about you?
Hey Jayson!
I think you mean Amersfoort 😉
I know the place!We use Nexa Autocolor in our shop, and we have the PPG delfleet line but that is only used for big trucks and stuff. The industrial work.
Ever worked with Nexa?
