Here is an update on the "Aluminum Rot (rust)" journey. Photo dump of before and after initial treatment. I haven't done any scraping, sanding, or grinding....just cleaning with Vinegar/Water and then a good soaking with this product called ACF-50, Anti-corrosive spray. It's good stuff! They use it on aircraft to fight corrosion on many different metals but especially Aluminum. It will creep into inaccessible areas and stop corrosion in it's tracks. It remains somewhat wet/oily and acts as a continuing barrier to prevent future corrosion from re-occuring also. Another task completed was to free up the rusted bobbin case, which the latch was rusted and inoperative on. I have a couple of small spots along the bottom I'm going to do a second pass of cleaning and preserving on and then it's on to actual functional cleaning, testing, and adjusting. I'm not entirely sure what I'm going to do about the paint loss on this one. It has a decent finish for the most part with good decals so I can't see an entire repaint being necessary. With the "Made in Canada" stencil on the back of the arm, I'd like to keep that original and just preserve as is. Well, after I get it sewing and more cleanup work, I can figure out the ultimate plan for the paint loss from there...no rush. Stopping the Aluminum corrosion was the immediate concern cause I didn't really know how much actual Aluminum was going to be lost in the process. Overall, I think we caught this one early on before much damage was done. I'll post a picture of the spray I used also. Enjoy your Featherweights!!
