Thread: ?'s about removing rust and prep.

Tweet

I have a car with surface rust in the engine compartment , the vehicle sat with no hood. Its a Vega and I want to eliminate all rust and paint. I plan on using por 15 and a black top coat.

I want to take the front subframe and inner panels off and was thinking of getting a small swimming pool and putting the parts in there for the rust removal. I seen this process on TV but forgot what chemical is needed. I know it was something simple you could get from Home Depot. Then add water and the electrical charge and a couple days later the rust was removed. Anyone know the process?

You can use a mixture of Arm & Hammer washing soda, Draino or Lye (probably the first is safest) with water in the tank. Attach the negative lead to the rusty part and the positive lead to the sacrifical scrap pieces of iron.

Ok I found the info needed but was wondering how it would work with 2 small battery chargers? How do I connect them so I dont reverse the polarity and short something out?

Just me maybe, but I have never been a big fan of the POR stuff for areas that will be seen. Somebody went nuts with it on the core support I have for my car and I can't get it off easily and the brush lines bother me.

"How do I connect them so I dont reverse the polarity and short something out?"

If the chargers don't have color coded leads (red=positive/black=negative) you can use a simple volt/ohms meter to test them, or hook the leads to a charged battery. The guage on the charger should indicate if you have reversed the polarity.

navel jelly will work .

Using this method , what do I use to Paint and protect? Will epoxy premier be ok? This process leaves the metal black.
