These coatings require the item to be pre heated, so that when the hot item is dipped into the powder a thin coat adheres to the surface. Because the sheet metal components do not retain the heat evenly, one gets an uneven coating that often leads to runs in the final stoving process. Unfortunately because of the risk of edge build up, all internal areas of the covers that contact the body frame will have to be masked off - these coatings are difficult to remove once they are cured. For proper application of 'Fine' coatings the electrostatic process is the only method to use - ie use a professional applicator, an M3 ain't no bloody fish hook! From experience you should note that even fine/thin coatings of this type can obscure fine engraving. If you want to find a suitable stoving enamel, do a Google search and contact a suitable manufacturer direct - note not their agents. Doing this in the UK has provided me with small test samples (1/2 pints!) of products that have proved to stove in the domestic oven. I offered to pay but all was gratis and much advice also offered.
