To use the spray paint you must craft the item first.

Crafting Recipe:

Spray Paint Item:

You can use any dye for the crafting recipe.

 

How To Use:

1. Hold the spray paint item.
2. Face a wall.

This is a capybara paint.

Temporary Version:

The spray paint will only last for 100 seconds then it will dissapear. You can't remove the spray paint, you will have to wait for it to dissapear. You can also unload the paint by going far away and going back.

Permanent Version:

The spray paint is permanent and will act like a block. You can break the block to remove the spray paint.
