[DML] Re: What to do with flaked epoxy in concealed areas of frame?

["cbl1739" <cbl302@xxxxxxxxxxxxx>]

Chris,

That is the basic concept on the rigidity of the black body,at the 
factory they injected High density foam in the cavities of the black 
body as it was being molded to give it rigidity in the crush or 
impact or safety zone areas...but the side effect is, it put in a LOT 
of extra weight,otherwise the black body would be like a eggshell,and 
would disintegrate as in part III of BTTF, when the train hits the 
Delorean. The Only area they did not add the HDF is the rear 
pontoons,and the reason for that is because the frame is in the belt-
line of the crush or impact zone,(and the fact that it was already 
rear heavy)but they did attach a HDF "bumper" to reduce the impact on 
the rear frame rail(behind the rear fascia)same as in the front,along 
with a aluminum beam attached to those foam "bumpers"(both front and 
back)
The only true metal area on the black body is on the roof where there 
is a bolted on metal cage to support the doors and the torque of the 
torsion bars and for rollover,also it (the Delorean) has a BUILT-IN 
roll bar made of HDF that works in conjunction with the metal cage to 
keep the roof from crushing in the event of a roll over,which because 
of JZD's "borrowing" from the mid 1960's "wide track" from the 
Pontiac Division and applying it to the Delorean makes it very rare 
to flip a Delorean.In fact I have heard of only one delorean flip-
over and that was done by a bunch of drunk college students durning 
some kind of college riot or party..they flipped it onto it's roof by 
hand.There still might be a picture out there somewhere.This was like 
10 years ago.
