Dachshund,
Have you ever considered painting your frame and under carriage, with POR 15? It encapsulates your bare metal and keeps anymore rust from forming. I found it to be very durable. Haven't had any of it chip or peel, since I painted my frame with it, 15 years ago. I used foam brushes, in cooler weather. Trying to avoid leaving tell tale brush strokes in the paint. That seems to work pretty well. Just something to consider. There are a lot of guys on here that have much more experience than I have. No doubt any advice that you choose to take, will be good advice. Good luck with your project.
