Cool product for those that buy and sell

[Pat Dilling]

I saw this product at SEMA, a good investment if you buy and sell cars. Saw the amazing demo, it finds filler and even tells you how thick it is. Helps you make a decision to buy or not, or negotiate prices if you find filler and still want the car. You can also use it show potential buyers that the car you are selling his filler free. Less than $90, would pay for itself in one use.

And all these years I have been using a flat, rubberized magnet sheet, to detect body filler.
Let's see, magnet free. This product $90.
Free vs 90. Free vs 90?
I think I'll stick to my magnet sheet.
This may, or may not, do a slightly better job of finding small Bondo or fiberglass patches, but my magnet (and lightly tapping any place it doesn't stick to, with a fingernail, to hear the tone of the tap) figures out the same thing.

So what about corvettes and kit cars...

Corvettes are 100% filler! NO magnets required.

What's old is new again . We have a homebuilt version that's gotta be more than 30 years old. I dunno how it's entirely constructed, as it's before my time, but it consists of a magnet with an analog meter attached to it. Direct magnets are great, but what these things can tell you is how thick is the bondo, how thick is the paint, what or if any metal is underneath the paint, and so on. If it's used in an area of the car long enough, especially if the car's been in an accident, you can construct a picture of the patched over damage underneath, even before looking under the body panel.

Search for a gadget called a "Spot Rot". It was a little plastic tube, containing a magnet and a calibrated spring plus a scale. Hold it against a body panel, and the pull from normal painted metal would pull the magnet to the zero point on the scale. A layer of filler would weaken the pull, and indicate the approximate thickness on the scale.

What would really be cool is to view the car in some sort of millimeter-wave radar that would "see" right through the paint and filler, and show only the underlying metal,
