I need to know what coatings are grease proof and good for outdoor applications, e.g. CV axles.
I want to sandblast or wire brush old Cv axles and coat them with something. I have considered powder coating but it is unclear if the epoxy will stand up to the elements or if polyester will resist the grease. Also unclear if POR products fit the bill. I suppose they could be plated but I don’t want to manipulate the spline area. If I find shrink tubing large enough I could get that too because it should stand up well. What about mixing the 5-min epoxy and spreading it on the rusty axle as-is?
