Hi All. I am a recent returnee to scale modelling. Given the size of my fingers 1/24 is the smallest I can go! I am retired but the average 14 year old would tell me a lot about modelling, the thing being is that I have totally re-fallen in love with it even though I am still pretty crap at it. So here (finally) is my problem. I have an Iwata Neo AB. I am using Vallejo Surface Primer, 74.601 Grey. I wash the model in a light detergent mix and then rub the surface down to remove any shine. I spray the primer on, let it go off for at least 24hrs and then carefully check it to make sure it is all smooth. Recently when I then spray the paint on (Vallejo) and sometimes even if I try and paint on, it comes out looking like oil on water !(best description I can come up with). My 'set up' is in the shed (very large) unless there is snow when I moved a lot of it indoors (wife not happy!). So, can anyone tell me what I am doing wrong? Is temperature anything to do with it? Or am I just an idiot, which would not surprise me!! Over to you experts
