A wise choice, sometimes a thumbnail and 0000 steel-wool is a good way to go ,
I once soaked a frame in vinegar and concentrated lemon juice for a few weeks. About half of the original paint came off but the frame was rust free. I used our guest bathroom bath tub. I now use a Jet Sled that I use to haul my firewood in from the wood pile in the winter.
I need to post a picture of the rusted tanks I soaked in oxalic acid. All I could see was rust and slightly some of the graphics, I had no idea what color the tank actually was. I soaked it over night and in the morning the tank was metallic red and the graphics were bright white. Not one bit of the original paint was lost, or at least what was left of the original paint. I'll get some pix tonight of the process and post them tomorrow.
That is killer! I think if I had more time I could probably have done it. Weather here has not been cooperative for outdoor work. There's always next year!!Frame came out nice! I forgot to post those pix of the Oxalic acid dip I did. Here's what I started with. Wasn't quite sure what color they were. Boy were these rusty!
Here's a pic the next morning. Holy cow, they're metallic red. Now all I need is a frame to go with the tank.
