End result

Good looking Volvo Gyula. Looks great in grey

Gyula Asztalos
Thank you for the kind words. The grey color is RAL7011 (The instruction specifies RAL7015) and I used a simple acrylic spary from the local hardware store. I also used a transparent gloss spray of the same brand. So no fancy stuff and not even a base layer (which I should have used...).
Unfortunately the result is far from perfect. As this was my first model, I made various mistakes during the build and had to do corrections on the cabin paint as well. I did my best but at the end, among other issues, the cabin paint is far more thick than the ideal. I think I learned a lot from my mistakes, so I hope I will be better on my next model.

I never was able to get any results with spray cans except making a huge mess and having a lot of drips and puddles on my model. I also think that hand brushing is one of the most difficult modelling tasks to master. I gave up many years ago and use hand brushing only for small details. Once you made the initial investment in equipment (airbrush, compressor and spray booth) and in time to learn the basics you can get pretty decent results. I am by no mean an airbrush expert but I am happy with the results I get with it much more often then using spray cans or hand brushing 😄

In general I give very little concern to the color callouts in kits, especially Italeri. First, it is my model and I will use whatever color I want, second, the color callouts are not always correct and third there is so much variety and customization in trucks so I am sure you can find an actual truck with your chosen color somewhere.

Looking forward to your next model.

Just dropped in to say hi.
Personally mate, as a truck builder, I would say that's pretty good, even as your first attempt. All Italeri trucks, have flaws. Usually it's an issue with the instructions, so to even get it finished, is an achievement!
I build a lot of AMT, Revell and Italeri, and it's only with experience, that you notice that you're being misguided by the instructions.
There's a few of us, big rig builders around, so feel free to ask questions and see some of the crazy things that we do? But as Goldman has said, it's your model, and you can do whatever you want, to it. The only time a colour is important, is it you're doing a specific livery? For example, DHL, FedEx, companies like that. I've seen way too many debates about this black, that black, the wrong silver, and so on? People need to realise, that sometimes, we builders have to work with, what we've got? I have to admit though, getting an airbrush, opened up a lot more possibilities for me. Mixing your own colours, can be extremely good fun. And the best time to learn, is right now.
So well done on a great model, and I look forward to seeing your next truck. Enjoy 🙂

Take a peek at that madness? We're all truly nuts, without a doubt! 😛

Thank you both!
I know this rabbit hole is really deep and some builders are on a really hardcore level. 😀
Currently my main challenge is to find the necessary time for this hobby.

We're all in the same boat, mate. However, the time will present itself, I'm sure. Winter is always a good time, but the temperature isn't so good, for painting. I purpose built a new mancave, that's temperature controlled. However, getting time to get in there, is another situation? It's best to remember, that this is a hobby, so build at your own pace? Everyone is different, but we all share the same passion.

Hey Bozzer! I'm mod mad, I'm just a three year old 😁

Gyula, for a first ever truck build, you did well. This hobby is about making mistakes and learning. Spray cans can be tricky, but some people get great results. Painting with a hairy stick can be tricky as hell, but we have a lady here that does wonders with those things.
I seldomly paint by the numbers, and most people seem to like it. and if they don't, the model is in my cabinet, not theirs 😁

If you eventually go the airbrush route, get a decent one, not some cheap knock off. And if you stay in trucks/cars, a 0.3mm needle is the minimum in my opinion. But opinions do vary from person to person.

Just keep building if you like it, ask whatever you want, there are great people on this site. Most of them will give you a friendly answer if asked friendly.
