Takoulis,
Sorry,But I only looked at the rusty metal. That really got my attention because I use electrolysis [water and a battery charger] and have dipped the Dish parts into a 2' x 2' x 4' deep square [ plastic only ] tank,for a day or two, with a commercial battery charger with 65 amps setting and the rust jumps off and the patina is still on the metal.
I started out with a 5 gallon bucket.
I did a Big Dish rust removal by making a box using 2' x 12' wood joist and adding a plastic liner to hold water and some Arm & hammer washing soda to cut the oil ,then put pieces of 12" rebar about 12" apart,in the water and around the box and and attached copper wire to all rebars to make a loop,which I apply the postive lead to the rebar and put the negitive lead on the rusty Dish for a day.
As soon as current is applied,look for the water to start moving around as a sign of a good connection.
The rust comes to the surface and attracts to the nearest rebar.
The metal being cleaned can not touch the rebar ,or it will weld together,but it needs to be as close as possible.
If the polarity is wrong the rust will go back onto the dish from the rebar.
Yes,I have a lid on the tank,otherwise if anyone [ grandchildren] stuck their hand in it ,they would be fried.
When the rust is gone ,the metal will be black from oxidation.
I wetted it wth water and sprayed Purple KABOOM on and brushed and rinsed.
I wipe dry/air hose it and a spray clear acrylic or a paint primer & color spray to seal the metal,otherwise it will start rusting as soon as the air hits it.
If the metal is fused / rusted together ,I apply T.P.Blaster for three days and tap with a rubber mallet,each day.
It will release the fusing if you are patient.
I love Rust.
