You are jumping all over the place. First you said, well it takes expensive equipment and you still have to have an oven.

Then you said, well I looked it up and the stuff isn't expensive, but you still need an oven.

Now you are saying, well, sure you can use a kitchen oven, but you can't buy the powder at Wal Mart.

Not one of those points are valid. The FACT is, you can do powder coating at home, in your garage, and get quality work if you do good prep work, and you do it right.
