My preferred paints are Alclads for metals and zero paints in general. Ill never use anything again other than these. Awsome products by Hiroboy.
The items I use above are what I use for prepping . I also use various fillers etc but have run out and need some more but an integral part of getting my final piece spot on. The items bellow are the paints in general that I use. A small selection of different black paints I use. Notice they are all Zero Paints!
For my air brush i only use this above. Can’t complain it’s the best but needs cleaning all the time. Before and after use.
