I read thru the post in the archive and thought I would give this a try.

I used a 55 gal plastic barrel,15"x37" piece of diamond plate steel 1/4" thick.(instead of stainless steel)I used 1/2 box of the Arm and Hammer and 45 to 50 gal of water.

I have this hooked up and running a test piece to just try the rust removeal.

How long do you leave the piece in?
Is there such a thing as too long?
How often do I need to change the water?
My new high tech. charger wouldnt even come on so I borrowed my dads and it only has a 10 amp charge. Is this enough?

Sorry about all the questions but some of these I couldnt really find a straight answer.

You leave the part in the solution, untill the rust is removed...

Too long? only if you're concerned with embrittlement.

Change the water? No.

High tech charger? It doesnt see a need for charging, so it wont. You need a charger that will put out if its needed or not. Make your own joke from here...

What is embrittlement? I should only assume prolonged exposure to the electrolysis makes the metal brittle.Am I correct?

I dont remember exactly how it works out, but yes, the metal can become brittle. This isnt a concern on an old gas pump though. Just remove the parts when they're clean.

Here are a couple pics of a Bowser 585 door after the first side was stripped.There was more surface rust than paint and you can see the results! I just wish I had found out about this a long time ago! For those of you who havent tried this you dont know what your missing!!!

I am glad to see some guys trying this out. That was one of my favorite ROTM's to write up!

I have also been using this method of paint removal ever since I learned about it here on Old Gas. Some of my non collector friends thought I Was Nuts (and I may be) till I showed them the results. The last thing I did was a complete Mobil/ Gargoyle 2 door oil cabinet.I took a non returnable 250 gallon Round Up chemical container made from heavy plastic, cut the top out of it and put the entire cabinet into the water, did half of it. Then turned it upside down and did the other half. Living on a farm and having a loader tractor made it a bit easier, but it worked great.
