At one time I was going to attempt to spray my own in an old Willie I had. Seems like the only place I could find the stuff was online. If memory serves me correctly I chickened out when I learned how toxic it was, that you needed a special gun and or a special pressure to spray it, and the aluminum prep was too much work for my taste. Good luck if you do it, and post the results if you would.

Also, the recommendation I got was to definetely clear coat it afterwards. It is supposed to make it less porous and last much longer.
