For this tutorial's "Environs" layer, choose Edit/Fill from the menu. Select Black for Use, 100% for Opacity, and Normal for Mode. Don't be scared if everything disappears. It's just hiding. Besides, you have been saving as we go along, so you're safe. (If you have chosen by default to create new documents with a white, rather than a transparent, background, you will replace it here with the black. The tutorial has been tested both ways.)
Double click on the Foreground color box to pick a green-grey, also known as verdegris. You see this color beneath the bird droppings on old bronze statues out of doors. Use the airbrush to paint the verdegris on the layer, leaving some black area for soot. Now choose an dirty tan shade and paint in the rust. Leave about half the space black between verdegris and rust. Save your work.
From the menus choose Filter/Distort/Wave and choose Square for the Type option. Then give it a Gaussian Blur with a radius of 5.


Corroded Variation
Next, make the "Environs" layer active and choose Multiply. Adjust the Opacity to your taste. In the example, the setting is 75%. Notice the difference between using the Multiply state here instead of the Overlay state.
Now you have the finished alternate corroded variation.
Here is the finished alternate tarnished variation.

Tarnished Variation
You can have yet another alternate version that is tarnished rather than corroded by using the copy you made of the "Environs" layer in Tutorial 02, (You did make it, didn't you?) 
When you have everything as you like it, File/Save the document. This is your Master file. From it you can create your choice of the corroded or the tarnished image by doing the following.
Ready to Show
From the menu, choose File/Save A Copy, with these options selected: Flatten Image and Don't Include Alpha Channels. The copy will be your Final version. Save it as a TIF file using LZW compression.
Now you can print this final version to a color printer or send to a service bureau for film. If you want to use the image on the web, then choose from the menu Image/Image Size, and change the dpi to 72; make sure the measuring units are in something other than Pixels.
