I think I agree... Though I'm not sure how to achieve that. I don't have any weathering powders or the like. Any ideas? Also, then the tractor bit should be yellow as a main colour also, right?!

Wow, didn't expect that! Thanks a lot for the vote of confidence, @RonBSM.Whatever phone you're using now, it will no doubt have some video editing capacity.
I think that if you can spare the time that you should make a little video on magnetizing because that is a minefield of miniature gaming, but if done well... total game changer for many. And you seem to have a real skill for that so a video would, I think, be brilliant for many. Me included.
