Cleaning a Body - Page 2

Thanks everybody for the info.

John -
I appreciate your nuts and bolts perspective. I did find a place in Jackson, MS and a place in Ball, LA that do chemical stripping, but I cannot justify all the cost for this project. I am now gathering up materials to do a rudimentary rotisserie and plan on doing this by hand. I probably will do soda blasting after the undercoating and sound deadener are removed.

I have also done a few cars in my time, but this one has an unusually thick layer of undercoating and I was just looking for a easy way out.

For undercoating removal, I use a wirewheel on an angle grinder. It does take a little while but, I found it faster than Duzac's method. You will get dirty though. I used four large pipe jack stands to lift the car about 3' or so off of the ground to where I could sit and work under it. I too was too cheap for a rotisserie. Have fun. BTW, my Duster's factory undercoating was almost 1/4" thick in some places.

Dwight, the method John Duzac described works well, albeit a little messy. My suggestion would be to get a drywall compound spreading knife for the larger flat areas. I started with oven cleaner after the big chunks were removed from my Malibu's underside. Then finished up with Super Clean, a good rinse, and final wipe down with cheap lacquer thinner.

If you do go the soda blast route, I believe you have to neutralize with white vinegar if bare metal is exposed.

Should be a piece of cake using a rotisserie. Good luck!

Here you go Dwight...an alternate method...

Wow! I thought I had an original idea!!

Dwight Southerland · 08-15-2008, 05:47 PM

My rotisserie may be wooden circles cut from sheets of 3/4" plywood bolted to the bumper mounts on the car. Not exactly a rotisserie, but at least you can roll it over.

Dwight: I saw the picture of the gut welding under the turck and in my wildest days would not get undet that truck! But I gotta tell you, this guy has a lot of nuts, or another way of saying it is nuts... Any way you choose to remove undercoating, the end result depends on the amount effort you put into the project. Spending alittle more time in the hard to get at areas will pay off when someone looks under the car. I call it pride... Good luck.

What are you building Dwight?

I sell an American made tool that is specifically designed to remove undercoating. After doing several cars with a torch and steel wool and solvent, this is the best solution. The specialized wheel has done 3 cars and still works well. It will also take off paint although it isn't 100%.
