The tutorial of Iron Man's homemade suit is as follows. Let's move your hand.

First of all, there must be production drawings, which we can download from the internet. I have demonstrated the mark6 helmet.

If you can't find a drawing, you can take one from here, print it yourself if possible, or draw it with thin paper.

After tracing down, cut out the drawings part by part and trace them on the eva board.

Then cut off the parts with a meat cleaver, and then glue them with 502.

When all the glue is ready, you can use white latex to add water 1: 1 to brush the helmet for 3-4 times, and then paint it. It is suggested to paint the background color with silver first, and then spray transparent red. Or just use scarlet. After drying, you will get such a helmet.
