Do you need to straighten anything? If not clean all old grease off then sand and wire brush to get off any rust and scale then lube white white lithium grease.
They are nice and straight. I was wondering if I can sandblast them or just a light hand sanding? Also, should I paint them so they don’t rust or just leave natural? Thanks!
I'm prettty sure window regulators and tracking components were zinc plated to inhibit corrosion. If you Sand or sandblast you might be doing more damage than good. I cleaned and lubricated mine with white grease. BTW I needed to replace a couple window track components. I found Classic Headquarters window track components to be high quality. Their components were not plated so I painted prior to installation.
