Thanks for the positive comment! It’s not really possible to eliminate the oxidisation, it’s inherent with Landrover lol. In my experience the best you can do is using a dual action sander or similar, try to remove as much as is possible. If it has all gone then polish the area with a fine grit pad before applying sealer/primer/paint. If it isn’t possible to remove all the oxidisation then just get as much as possible and use some epoxy to build up the surface and try to seal it. Without oxygen it will slow the process a little. Definitely one of the Defenders Achilles heels!
