The first step in weathering is finding a prototype or in my case multiple prototypes. I found pictures of a particular model that i liked and wanted to model then comes the fun part, The trip to the hobby shop. I went in knowing exactly what i needed for this model which was an Athearn PS 2600 covered hopper this is the exact model i chose.
Now if you are going to do what i did and make this a csx model you will next have to remove the decals. All i used was my exacto knife and carefully scraped away the L&N and the original number of the car. Then comes the part i hate which is putting the new decals on. After that and after you have added any after market details (assuming that you may or may not have) you are ready for the weathering process for this model specifically this is all the materials i used.
First what i did was take a mixture of white acrylic paint and water mixed them together and with my airbrush (which you will need) i sprayed several coats 2 specifically on each side then i went back with another mixture of grey and burnt umber as a 'General road grime' after that i sealed the model with clear coat and took the trucks off. Then i took the model master acrylic airbrush paints and dry brushed the general areas where i was gonna have my pitted rust. Then i mixed in my airbrush the model master acrylic i used for the general rust and sprayed the whole car with several coats 3 i think. Then i went over that with the dark earth MMA airbrush paints. After that i mixed the burnt sienna and burnt umber regular acrylics and made a wash which i went over the whole car with. Then i went over the areas with the previous established rust was gonna be. Then i mixed rusty brown and light rust AIM weathering powders together to for a redish rust color went over my rusty spots and sealed with dullcoat. I just used the burnt umber/Burnt sienna mixture for my trucks and wheels and used the powders over that. And finally to add some more realism i used a little csx tan color to simulate a spilled load on the trucks. I hope you find this helpful and please forgive me for my poor grammer it is late XD
