How to make welding lines

First I want to say that this isn’t the only or best way to do this; I’m simply showing the way I did it.

1.What you’ll need

  • Epoxy putty ( it doesn’t have to be milliput, just make sure it’s the kind that’s a bit like clay since that’s much easier to handle)
  • Hobby knife (or any other flat thin object that you can use to shape the milliput)

2.Mixing and shaping your putty

Take a little bit of each stick and mix them together like the way the instructions tell you to.
When your epoxy is all mixed and ready to use, roll it on a flat and preferably clean surface until it looks like a sausage.

3.Preparing your parts

When you’re applying the weld line on a place where there is normally a panel line, it won’t be a problem, but if you’re trying to get it on a surface that is normally flat, I’d suggest carving a panel line first.

4.Applying the weld line

Take your epoxy sausage, cut off the appropriate length and put it where you want it. If you’re not working on a big scale kit, your sausage will probably be a bit too thick. Use your finger or a satay stick (or a toothpick) to push the epoxy putty in place so that it sticks to the surface.


Then take your knife and gently cut off the excess putty until you feel the size is good. Now take your hobby knife and use the blunt side to push in the indents so that it looks like it’s welded on.

Let the epoxy cure and voila, you have a nice looking weld line.

I hope this tutorial was of use to some people.
