Other parts can be handled better with wire hooks. Some parts can sit on a metal grate or tray. Find a way to move coated parts into the oven without knocking the powder off. Pull the part(s) out of the oven, and wipe down with a clean rag. Wear gloves and do not touch parts with bare hands before applying powder. It is best to pre-heat parts for a few minutes to bake out any moisture or oil that may still be present after normal prep. That takes some time, but not nearly as much as waiting for primer and paint to dry. Powder-Coating does require stripping parts to bare metal.
The Eastwood powders just seem to apply better with fewer problems.
The Eastwood Gun worked well and their powder paint is superior to any other brand that I've tried. We bought a new toaster-Oven for the kitchen so I could have the old one to use out in the shop for powder-coating. Their gun requires compressed-air and a standard electrical outlet to run. Many years ago Eastwood ran a sale on their entry-level HotCoat Powder Gun and Starter Kit. As soon as the parts are cool enough to touch, they are ready to be reassembled. Powder-coating is one way to refinish parts that required almost no drying time. Prepping for paint, waiting for primer to dry, then waiting for finish coats to dry might significantly delay being able to reassemble those parts. Refinishing small parts such as carb castings, headlights, brackets, linkage, etc. Sheetmetal can even be taken to a body shop if the damage appears to be more than you want to deal with. Different color parts finished separately always look much better than any masking job. Disassembly may be easier than trying to mask everything. It is generally easier to finish small parts and all sheetmetal parts separately. Some people can feel if a panel is smooth, others like to spray a quick coat of primer to see if more work is necessary. Sheet metal parts are a lot more difficult to finish well. It takes little effort to make the cast iron parts look good. Now is the time to decide how much time will be spent on bodywork. You can even use liquid metal epoxy for some repairs. It is possible to braise or weld cast iron. Now is the time to do any body-work or cast iron repairs. Keep scraping and sanding until the finish is smooth to touch. If chipped areas continue to flake-off, the old paint is loose and needs to come off. Sand edges of chipped areas to blend with adjacent surface. Small picks scrapers and stiff brushes will turn up a lot of areas that need additional attention. Use whatever is handy and seems appropriate to get into the nooks and crannies. The tractor will soon look a lot better, but there will still be dirt and loose paint. The spray nozzle will also blast away any loose paint. Painting requires removal of all dirt and grease so power washing may be the best way to remove most of the stuff that collects on any tractor. Frequent power washing will thoroughly screw up carburetors, distributors, air cleaners, gauges, and electrical components. Power Washing is not the preferred method of cleaning your tractor on a regular basis. You will need some scrapers and wire brushes to help remove caked-on gunk. Remove or cover the carb, distributor, and electrical parts and give the tractor a good power-washing. If all you want is a better looking tractor, stripping everything to bare metal is not necessary. If you want a show-quality finish, there is no substitute for stripping everything to metal. Lots of time and effort was spent on the sheetmetal, but the transmission and rear castings were just a quick spray-over. In that case, doing a quick dust-off and respray of some running boards, or pedals on another tractor is better than dumping the extra paint on the ground. There may still be times when there is a little paint left in the gun after spraying some parts. Every bit of time spent (scraping, sanding, cleaning) is time well spent.
Painting over dirt and loose paint is just wrong. Surface prep is where the average paint job fails to look as good or last as long as it should. Painting tips from me will be about as basic as it gets, I'm no expert.
