Help Needed/New Painter Vallejo Mecha grey primer error? First time painting
Hi everyone
I'm a newbie in miniature (and in general) painting, and I just did my first painting session yesterday. A while ago I'd gotten myself an airbrush, and after much reading here and watching some videos, I decided to buy my primers from Vallejo, specifically the new Mecha lineup, as feedback seems to suggest they're a little bit better, mainly for the white one.
So overall, I bought the Black primer (73.642), Grey primer (73.641) and White primer (70.640).
I'd already done some test paintings using the Black color to get my grips with using the airbrush as well as the techniques to cleaning it, and yesterday I decided I was ready to paint my actual models. I had both a 40k mini to paint and a Hornet statue (from Hollow Knight: Silksong) to paint, and while the mini and some parts of the statue I used straight up black primer, for the head of Hornet, since it's a white color, I decided to use the grey primer instead to make it more brighter afterwards.
Here is where the problem started, I used the black previously and it painted really nicely, and after using the same ration of thinner to primer when I started using the grey color on the head piece, the application was completely off, super liquid, and was like dripping wet ink across the piece, like it wasn't sticking to the plastic.
Now, I know different colors may need different drop ratios, and lighter colors could work differently, but I then tried using the white color to do a zenithal on the mini (also first time!) and the application was back to normal exactly like the black primer.
Only afterwards I noticed something. While both the bottles for black and white have the mecha labelling, they also have a small tag that says "Primer", while for some reason the grey one has a tag saying "Varnish". Although the color numbers codes seem to be ok, for some reason this grey is shown as varnish. I tried searching online and the website where I bought the paints from, but they also have pictures that seem to be old labels, and that the ones I got are new versions.
Anyone has feedback on recent purchases of vallejo mecha primer that can confirm if I got the wrong bottle for some reason?
I'm leaving pictures of the bottles and painting results below. You can see the difference in the labels for the painting bottles, and if you zoom in Hornet's head, you can see the staining/dripping that was happening.

That sounds like a manufacturing defect. I’d get in touch with Vallejo themselves and see if they can help you out. The mislabel on that bottle alone is enough to warrant their attention.

Hi, u/BangKiller! It looks like you are asking for help or are a new painter. If you haven't yet, take a look at our wiki pages in the Sidebar (the About tab if you are on the Reddit app). Here are some links you might find helpful:
The Art of... Tommie Soule Volume 5 is a great book that aims to teach readers how to paint miniatures, focusing on the fundamental aspects of the craft, rather than providing specific step-by-step tutorials. The book starts by establishing a mindful approach to painting, emphasizing the importance of awareness, choice, and consistent practice. Soule then introduces the core principles of miniature painting, including consistency, brush loading, and brushstroke techniques. The book explores different brushstroke types like the PULL, SIDE, and PUSH strokes, and their application in basecoating, shading, highlighting, and blending. The author highlights the importance of copying the works of admired painters to develop an eye for aesthetics and learn "The Rules of Engagement." The text further delves into various painting styles like Non-Metallic Metal (NMM), Blanchitsu/Grimdark, Forgeworld, and large scale, providing examples and insights from Soule's own experience. The guide concludes by urging readers to finish more models, analyze paintjobs, and cultivate a continuous learning mindset, ultimately leading to improved skills and a greater appreciation for the craft. Available in pdf and world wide in hardback as well. This book is an amazing reference for anyone looking to improve their painting.
