Curious about your prep process for repainting ... what do you do to kill any rust you encounter ?
Mostly I use a bead blaster, but various wire brushes also come in handy.
When I run into really bad rust, I use POR-15 Metal Prep, then follow it up with one of their Top Coat paints. The Top Coat is a new product for them and me, but I've had very good luck with the Metal Prep and their old two coat system.
I stopped using acetone when I learned it was a carcinogen. That and the can always seemed to be empty when I reached for it, as it's very hard to seal it in. My local bulk fuel and lubricant supplier also stocks cleaning solvent, and a five gallon can lasts a looooooong time, even if I just leave it in the parts washer. I also have an old brass bottle with an air fitting on it that lets me squirt the stuff on bigger parts that won't fit in the washer. Got it years ago at Brownells, but can't seem to find a link to it now.
The most important step for pre-painting prep is to always start by cleaning the parts with soapy water to get off the oil and grease. If I skip this step any wire brushing or blasting just drives the oils deeper into the metal, and they'll come out as fish eyes in the paint. A bucket of hot water and a couple tablespoons of Dawn dish washing soap get things started on the right foot. I repeat that cleaning after all the sanding is done. In fact, I'll usually add a few drops of Dawn to the water used for wet sanding, as it helps keep the paper from clogging. Anyway, clean water rinse, blow off with filtered air, one last wipe with the dust rag, and it's ready for shooting.
Now if I could just find a way to keep the bugs out of the paint...:shocked:
