To fill the oval hole in the boiler jacket, I use some non-stretchy tape on the outside, well rubbed on around the hole and 5 minute epoxy on the inside, rocking it back and forth until it gels.

After the epoxy hardens it gets a layer of epoxy saturated paper or other mesh on the inside for added strength.

When you peel off the tape you'l be amazed at how little filling and priming you need.
