RJ London Vs. Tamiya TS Spray Paints for Gunpla

Gunpla modeling is an expensive hobby. That's why modelers are always trying out cheaper alternatives that not only would finish the job but also make the finished product look really good. Case in point: cheaper paints.

I tried out some RJ London spray paints since Tamiya spray paints are expensive. Not to mention they're only available in 100 ml rattle cans. Anyway, the one on the left is sprayed with RJ London silver grey and  dull lacquer on top. The one on the right is sprayed using a Tamiya TS-66 IJN Gray (Kure Arsenal).

As you can see, the one on the left looks glittery and has frosting-like material all over it. On the other hand the part sprayed with Tamiya looks clean, smooth, and has a matte finish. I don't know if this is just a case of old spray cans that expired, or probably because RJ London paints are made for other stuff (like hardware, etc.), or I'm just an idiot. One thing's for sure, though. I won't be using RJ London paints for a while. Besides, Tamiya paints are especially packaged for model kits has yet to fail me.
