In this chapter of the Breathedge game guide, you will learn where to find the lead and paint required to create lead paint, and later - a spacesuit.
To acquire the paint necessary to make spacesuits, you'll have to head below the base, towards the orange light.
There you will find the smuggler (1) - take his eye and bring it to the nearby safe (2). Inside, you'll find the lead paint blueprint.
To make lead paint, you need paint and lead. You will find both components by following the orange light to the largest broken fragment of the spaceship in Sector 1.
The paint and lead can be found inside, floating in space. Take as much as you need and, if you run out, you can come back for more.
