Reasonably inexpensive TUNGSTEN "grit" is available online - I
bought some on Amazon.
This is poured into center sills or under the floor and it's
denser than lead, not dangerous, etc.

Consider using thin sheet brass or lead under the deck

available. Don't wait until the car is painted and

work coupler and truck issues for that matter).
significantly denser than brass. Titanium is rather less dense
than either. I agree with Ben that lead is an excellent
choice, especially in sheet form. You can readily buy this
from roofers' supply stores (sometimes plumbers also) even if
your local Big Box no longer carries it. And an advantage of
lead is that it is so soft, you can readily "forge" pieces to
fit where they need to go in an under frame. You barely need a

dangers of lead. Well, lead in metallic form is not dangerous.
It does have lead oxide on its surface, so do wash your hands
after handling it, but beyond that, not to worry.
