For MJR and others. Here are pictures of the three parts that I have corrosions issues on. The first couple of pics are corrosion issues on the ejection seat armrests some, have deeper pitted areas than others. The rest of the pictures are pitting and corrosion issues on gear doors. Two different metals two different issues?
I’d have no qualms about hitting that lot with glass bead, those arms wouldn’t take more than 5 minutes. Are the parts for a flyer or static? If you were local I’d do all those parts at home while you waited.
The arms would look like this afterwards:
The pic shows on here as at least twice actual size, in reality it looks much smoother.
Bonus point to anyone who identifies the (motorcycle) valve cover 😉
Chemical treatment sounds promising – might give it a go, but I still think your best bet on simple items such as castings etc is a good old fashioned blast clean with aluminium oxide.
Al Oxide is too harsh for aluminium parts, it’s usually used on heavily rusted steel castings.

Then there’s ebay 😉
I was contemplating that today…;)
The real fun is when you put it back together, complete it, and there’s bits left over
There are never parts left over.. because there’s a trashcan at the end of the workbench…:D:cool::diablo:
