Is this a fair price to refurbish AC hoses.

Sorry twister360, I am not yet competent in AC hose crimping. I just have the parts and tools. Plus, too many "in work" projects already, and trying to keep the wife from fussing. My point was that any full-time AC Guy should have such tools. Used to be you could take them to a hydraulic shop, even NAPA, and get new hoses made fast & cheap. Some still find that locally.

I only use rust converter when I have pits you can't sand out. Most steel tubes can be sanded to bright steel by hand w/ sandpaper, or worst-case w/ a wire brush on a drill (wear glasses!). Then, primer and top-coat. Since that tube gets hot, perhaps use 500 F engine paint. I have used Rust Destroyer since claims 800 F and both etches and converts rust if any small pits left. Seems to work, but Home Depot and Ace stopped carrying it.
