As in lead filler - can it be detected under paint with a magnet? I have zero experience with lead and know that someone here knows . . . Thanks, Steve
Just dont put too much on one side the car will lean and be a dead give away that there was body work done. Just kidding
Lead,Brass,Bronze,etc are not magnetic. Depending on how strong the magnet is,you can detect the steel behind filler,but it will have less pull. Real weak magnets are first choice,they will barely stick over thin filler. Someone used to sell a tool,that would measure the thickness of filler on a panel.The price was reasonable,so i assume they were using magnets.
My materials professor at Wichta State University said that steel, iron, lead,and brass were all magnetic. I thought at the time I was paying a lot of money for bull shit.
You were probably right. I'm sure his statement was justified by some long winded molecular theory about Neutrons and Protons and blablabla. In the real world,if it doesn't stick to a magnet, it doesn't count as being "magnetic".
True in static state, but introduce motion and induction takes place causing magnetism. If it conducts electricity, it can create the field. Flatman
everyone's right...if it wasn't magnetic, then how could the Mythbusters re-direct a bullet's trajectory using magnets?...but in our line of work...nope...you can always do the tap test on spots you think have body filler, lead has a much duller sound than body filler which has a bright crisp sound when tapped or flicked with a finger...kinda like finding a stud behind a sheetrock wall...
Only if you go to MagnetWorld and buy a special lead magnet ... Better pick up an aluminum and fiberglass magnet too while you're there...they're all sold in the same isle as the bubbly water for your level.
Not to hijack the thread, but is body solder pure lead or is it alloyed with something else? I always thought it had some tin and other goodies in there too.
The percentage of tin in it varies, I forget which one you want for bodywork, something like 15% tin maybe - I'm sure someone here remembers better than I do?
Hey, Body solder (lead) is usually made up of 30% tin and 70% lead. Really good body solder also, has some antimony mixed into it. Swankey Devils C.C.
Antimony, like that stuff you have to give to your ex-wife in order that she may live a life she's accustomed to?
IIRC the 'Bond Tech Episode Pt1' they stated they were using jacketed steel slugs (with gilding metal / copper jackets) to maximise the possible effect.
In my experience, lead filler is non-ferrous, meaning a magnet won’t help you detect it through paint. Since lead doesn’t contain iron, the magnet won’t attract it. You’re better off using another method like sanding a small area to see if it exposes any lead. Just be cautious due to lead's toxicity.
So if the car is parked, its non-magnetic........but when you drive it, it becomes magnetic ? Just pokin fun. I learn something new everyday, and sometimes its things I used to know.
For as strong as Superman is, why didn’t he have a lead lined cape? Or suit? Things that made me wonder as a kid.
