I repainted and added rust to my witches' cauldron. Kudos to dave the dead for his oatmeal and sand technique for adding rust to a project. Here is a link to a before pic, flat black painted plastic.
After rust and repaint
Here is a video of it nearly finished.
The order of painting was black, orange textured, brown textured, purplish brown (accidental mix of red,brown, drab green and black that turned purple. I thought it looked "witchy"). Gray dry brush, flat black dry brush to make the orange less orangey and then flat black areas spritzed with a water spray bottle to add runs to make it look like it's leaking at the seams. I applied the middle blotches with a sponge.
To get textured paint I just added sand and oatmeal in it like dave the dead, did.
