Durable and nowadays just as beautiful as 'wet' spraying. That is powder coating. A highly professional branch of sport where you need a lot of equipment and things. Leave that to the pros! Or not?
Powder coating itself is nowadays an option. But it has its limitations for DHZetters.
Vocor Tools can supply DIY powder coating equipment and has a crystal clear story on the site.
And after reading that story, you can decide to powder coat yourself after having practiced enough. Then you can protect parts of your classic car or motorcycle yourself for eternity.
But never use the oven in the kitchen to bake off your workpiece. Because that is very much at the expense of the next apple pie.
