Lee...you can use the same 50/50 mix as the wet for wet sanding...just apply and sand. I used it to restore my Lion miter knife, Delta 6" jointer and old Darra James table saw top and it worked like a charm...just prepare your shoulders and arms for the exercise... :grin:Here are a couple pictures. I have soaked the rust with Stick's 50% Acetone 50%ATF over the last few months so I think the rust is soft and well soaked.
I am now thinking skipping the 220 wet dry paper and going straight to 320 wet or dry or maybe just a green scrubber. I have had good luck with 5% vinegar in the past. I don't if it would be better than the phosphoric acid...30%.
Hi gdonham1I have never had rust so bad as that but I got a used lathe that was pretty bad and I used a combination. I used a random orbit sander with that 3m non woven stuff you can use for sanding. I used the medium (Red) and put that on the velcro of the sander and used Topsaver. You can get Topsaver from Amazon. The sand paper will really mark you up and will take forever to get it down to smooth. I have also used very fine and fine diamond stones to lap a friends lathe that was pretty rusted. I used water for a lubricant for the diamond stone. I cleaned it up with mineral spirits and then applied the Topsaver. I use the Topsaver on all my cast iron and it never rusts. I live in east Texas with a pretty humid atmosphere. I also buy cheap cotton table cloths at Bed Bath and Beyond and cover my equipment to keep dust and bugs off. Occasionally I get a bird fly into the shop and they poop every time they flap their wings. The cover keeps from having a black spot caused by the birds or a dead bug dying on top of the cast iron.
I'm not suggesting anyone should take a bath in Acetone, but the reality is that it's a normal part of your metabolism; your body produces the stuff.
Occasional short term exposure to smallish quantities isn't going to hurt you.
Folks that work with FRP are using Acetone daily and for the most part the other resins and chemicals are a a lot more of a heaalth hazard than Acetone.
It is however a very volatile and flammable product. A lot of ventilation goes without saying!
