Hello everybody,

after I'm feeling a little better again, I want to get back in touch today and draw on my recent conversation with my friend Heinz Wagner, which first focused on the required consistency of Vallejo paints, which are to use for the Airbrush technique.

As I have learned in the meantime, it depends on the correct use of language, whereby in his opinion you have to differentiate between sprayable and ready-to-spray, what is not the same and is often confounded.

While the Model Air paints from Vallejo were specially developed for the Airbrush technique and are basically sprayable, the Model Color paints were specially developed for the Brush technique and are therefore much thicker, which one should know and also note. However, this does not mean that Model Color paints are unsuitable for airbrush technique. One only has to dilute them accordingly so that they achieve the required consistency and can be applied with a spray gun.

Therefore one should check the viscosity of the respective paints before each spraying, regardless if Model Air or Model Color is used, and dilute them if necessary with Vallejo Thinner, so that they are ready-to-spray, which can be tested with the Heinz Wagner Method already described.

But already at the name of the Vallejo Thinner one can start to ponder because one can find four different data for one and the same article as one can find on the Vallejo-Website, which is available in four different bottle sizes as required, but what you need to know:

71.261 (17 ml)
71.061 (32 ml)
71.361 (60 ml)
71.161 (200 ml)

Accordingly, a correct mixing ratio between paint and thinner is crucial for ensuring the ready-to-spray consistency of a paint. And that is evidently the crux of the matter, especially since there is no patent remedy for it, but only empirical values that one can believe or not ...

Therefore, one should not trust a mixture ratio that one has not tested himself and found to be good, based on the famous quote: Do not trust a statistic that you have not falsified yourself.

For example, by Vallejo a ratio of 1:3 (Thinner to Paint) is recommended for the dilution of their Model Air series, but what can never be right according to my current level of knowledge, to be able to spray these paints easily.

And also the filling up the Vallejo dropper bottles with Thinner, as it was recommended in the video by Jens Kaup in Reply #1924, does not have the desired sustainable effect.

As one can see in the following image, the dropper bottle Model Air (71.130), filled up with Thinner a year ago using this method, is not ready-to-spray, which is clearly proved by the too small color point < 11 mm, when using the Wagner test. An airbrushing with this paint would inevitably clog the spray gun, which is why one shouldn't even try it.



About this I recently spoke with Heinz Wagner, who has not been wondered at my initial failings.

In order to get a feeling for a reasonably "normal" airbrushing at first, he initially recommended a mixture ratio of 1:5 (Paint to Thinner), which results in a much thinner, but therefor a ready-to-spray paint, what is indicated by the larger color dots (right) promisingly.

So I should first carry out the exercises described on his Airbrush CD and remember to occasionally clean the nozzle cap with Vallejo Airbrush Cleaner to avoid cloggings effectively.

Although I didn't take it that seriously at first, it seems to me that it is absolutely necessary and helpful for becoming more secure. However, the paint seemed to me to be a bit too thin, which is why I once tested a mixing ratio of 1:3 (Paint to Thinner), which led to a color point of Ø 13 mm, what suits better in my opinion.



And with this mixture ratio I will now carry out some exercises.

Hello friends,

first a short health update. After the complaints shifted more towards the shoulder, I went to a specialist once again, who has sent me to the MRI check to clarify the indication of a Rotator cuff lesion.

The radiologist interpreted the scans, among other things as laceration of the supraspinatus tendon (transmural anterior defect, 1.0 by 1.0 cm). In addition, another tendon (Subscapularis), the local Bursa, and the Biceps muscle are inflamed.

If interested, this image shows the muscles/tendons of the Rotator cuff.

"Just" a rib bruise, My eye! - as it was initially said by the family doctor, Nobody is perfect!

What that means I will hear next Thursday ... I just hope that I can get around an operation.

But now back to the Vallejos. I was interested again in the consistency of the re-ordered Model Air paints, which I therefore tested with the Wagner method.



As one can see, the diameters of all three color points are below Heinz Wagner's critical limit of 11 mm and should therefore not be ready-to-spray.

As a result, one would have to dilute it by adding Vallejo Airbrush Thinner to avoid clogging the nozzle. In any case, I now know how things stand, what is very helpful already.

Oy! Still sending good vibes your way!

Thanks Becky,

wait and see ...

My best wishes Manfred for a speedy recovery with therapy versus surgery.Bad enough to get hurt, but to add in surgery is just getting double dipped.

Thanks Ed for your good wishes,

hopefully a surgery can be avoided, press your fingers crossed.

Hello friends,

last Thursday I was with the doctor who had referred me to the MRI. After looking at the CD, he said that it was a complete rupture of the Supraspinatus tendon close to its enthesis, what has rather sobered me up. He then has explained the conservative and surgical therapies to me, leaving the decision up to me, as well as the offer to get a second opinion.

He showed me the recommended Shoulder arthroscopy, possibly with a seam of the Rotator cuff, on the model and in a schematic video, which looked relatively harmless and remembered my knee arthroscopies.

That would mean 1-2 days in hospital and then wearing a Shoulder abduction splint, for about 6 weeks, including physiotherapy ...

Although I initially agreed to the operation, I've started now mulling over it again, especially since I now have hardly any complaints and can actually move my shoulder as before.

However, the doctor pointed out that the torn tendon would gradually shrink, so that later one could not operate it this way, what one can believe it or not.

What also made me wonder was his statement that I could still take my time with the operation and that September/October would still be okay ...

If one then considers yet that the doctors in Germany often recommend an operation far too quickly these days because one can earn a lot with it, I'm actually on the verge of getting a second opinion from another shoulder specialist.

[eagleclaw4935]

If I were you. Get the second opinion.

I also think so, Ed.
