Been some time hasn’t it?
Today I will be going over Granual effects which is often used to give either a cast iron effect to your model or a general rough surface to imitate that which happens the rust starts to eat away at ex a car beneath the paintjob (see picture bellow). for this tutorial I will primarily focus on making the rustic base.
For this you will need the following:
- Un-painted Model of your choice (I used a Frame Arms Greifen)
- Modelling putty (Tamiya)
- Plastic glue/cement (I use GW but there are other brands that can be used)
- Sponges (cut in smaller pieces to get better controll if you use a dish sponge)
- An old brush
- old Paint/ half-dried paint
Ok! So the work is In reality fairly simple but takes some planning to do. What you need to do before you start is to figure out where the roughness off the rust will be on the model to make it look natural, which will be areas that will be in contact with lots off ellements such as water and dirt, but will still not get grinded away and be left alone for some while, such as areas near the feet of the model or arms. Once that is done It’s time for you to start using your tools.
There are a couple of different substances to use but from what I have tried, plastic cement/glue and putty works best, semi-dried or really old paints might also be used but take what you have.
To use glue (which isn’t very visible on camera apparently) simply find a place where you think the effects would look good and natural, put a small blob of glue and start dabbing it with your piece of sponge. If you want more control or smaller amount, use either a glue bottle with a thin metal nozzle or a toothpick to apply.Also, if the glue starts “webbing” like in the last pic, just remove the webs when the glue is dry.
The other two follows the same Idea of finding places and dabbing sponges but will be easier to spot after it’s dried, though it might take some more time to dry as opposed to the glue.
For making the Cast Iron effect you follow the same steps as presented above but you cover the whole piece instead of just an area, though I advise you to use this carfully if the panels have lines that you want to keep.
Once the effect is done and painted it will look a little something like this:
I will get back to you on how To make rust effects for another day, until then, have a great day!
