Fill Me Up With Contrasting Colours

Ever wonder why model filler comes in different colours?

Its the same stuff just in different colours.


The theory is this. You should use a filler of a contrasting colour to the job you are filling.

As you can see on the back  of this loco it has been primed with white acrylic primer and then green filler and left to dry.

The next example is a side on view of some filler that has been rubbed down with some 1000 grade wet and dry paper used wet.



The contrasting colour lets you see when you have feathered the edge of the filler into the body.

In this case its left filler just in the groove in the tank side. The groove shouldn’t have been there in the first place but the 3D printer had a little wobble and I am using up development prints to experiment with.

The next stage is to add either undercoat or the final body colour. Having sprayed both bodies with white primer to better show any blemishes the cabs were masked off as the upper parts of the interior will be cream so the white is the ideal first layer.

The green engine has body colour added straight on to the white. The green I had is a bit darker than I wanted and adding it to the white lightens it a bit.

Alternatively the red engine has had a coat of brown primer on top of the white. This is a bit of opposite logic to above. Adding the red body colour straight on to the white would have made the red look more pink so the brown layer better preps for the red.

The red hasn’t been applied yet as just as I was getting to it the weather went scorchio and the paints were going off before they could be sprayed.

That’s it for this little interlude. More of these locos as they develop.
