The fountain of youth for metal. I show how I turned back the hands of time to remove surface rust from many of my 74 Nova parts during the restoration. The pics are just some of the many parts I rejuvinated with this product and process.
74 Chevy Nova Update 100 - FINAL PAINT (Lots of Timelapse video)
My Day at the paint booth! Lots of time lapse in this video of every step I
took to get the 74 Nova painted. If you are wondering why I taped green
tape to my clothes is because I wanted to make sure my clothes do not flap
and touch the car while painting. Its tight against my body.
rust chemicals compared, phosphoric acid vs deoxidene vs vinegar vs mag wheel cleaner
One piece of sheet metal with fresh surface rust is cut up to be treated
with a range of chemicals. The rust is treated with five minutes of
scrubbing with a fibre brush. chemicals used are white vinegar, Deoxidene
containing phosphoric acid, and mag wheel cleaner. I also performed the
five minute brush scrub with water so we could see how much the chemical
enhances the rust removal.
Using citric acid for rust removal
Citric acid can be bought from drugstore (they use it in jelly or such to
adjust acidity) but it is very expensive there. Therefore Finnish rodders
buy it from some agriculture-store. It is not expensive. Officially it is
used as pigs obstruent! I dipped those parts in citric acid for overnight,
next day brushed it with wirebrush and flushed it with water. Then again
back to citric acid over night and wirebrushed + flushed it next day.
Flushing is important, you'll want to get all acid away, otherwise steel
will turn to yellow.
You can't use this method on all parts because of hydrogen embrittlement.
So no pedals, frames, brake drums, engine blocks or such to citric acid!!!
And yeah, parts should be clean -I've cleaned 'em with fuel- because grease
will neutralize acid. Ratio was 3%
Parts must be dried soon as you get them flushed, I quess you guys know

Proper automotive rust repair
A quick video that follows a rust repair I did on my daughter's car. The
right way of dealing with rust is cutting it out and welding new metal in,
no other method will yield any lasting repair. And no, rust can not be
neutralized completely on a car, there are just too many places you can't
reach... No miracle product, no shortcuts....its just a long process...
Don't ask about price, I don't do those kinds of repairs commercially,
there is just no way to make money with those at a fixed price...
