Outstanding work. From California USA. I also have a1968 MGB with chrome wire wheels.

Nice job. For those difficult to reach rust spots, try wrapping a ball of aluminum foil on the skewer end. At minimum it should remove the rust stain from damaged area.

Mother's chrome cleaner is a good chrome cleaner,,but if you ever get a chance to order (( Street Juice/ Them Thangz)) Chrome Cleaner Chrome or Gold Cleaner you want go wrong,,as far as cleaning the pits on them get you a angle toothbrush that way you can get in deep cleaning,,street juice/ them thangz is here in America,,trust me you want go wrong,,you'll love it..

I forgot to mention to give your lovely wheels a ceramic treatment from Flitz products it comes as spray bottle, to keep dirt and rust away.

WD-40 on chrome? Why not wax?
