I am no expert and have no business giving advice haha so now with that disclaimer out of the way, to me, comet wash felt like wet sanding for dummies. It has a mild abraisive, so I felt like it helped remove any chunky porous patina areas, smooth everything out and essentially removes your foggy layer of clear coat that has been eaten by the sun. Was told by friend/mopar guru the linseed just seems to preserve what’s remains. Once again, not an expert but I am assuming due to it being an oil, it starves the remaining Patina/rust from oxidizing further. :)
