Hello,
Iīm sure the old stuff used by TRIUMPH between wings and body works but one
should consider to use some of the new materials now availible.
As far as I found out the sealing should:
1. Seal metal overlaps against water. Not only against splash water but against
water found in a gap between two sheet metals bolted together because of the
capillary effect. If you donīt do anything against it there will always be
water
as soon as your car gets wet and it will stay longer there than anywhere else.
This is a good starting point for rust.
2. It should be possible to paint over it.
3. It shouldnīt get hard with time. All bitumen based materials get hard with
time, crack and make way for water. Thatīs right the thing we donīt want.
4. Wings/body parts should be easy to remove even after some years.
At car parts supplyers you can find the right thing which is called "sealing
band" like the stuff from Teroson and others. I used it on my TR 6. Itīs a 2 X
20 mm slightly tacky sealing compond. You put it between wing and body any
places where the two touch each other. If someone wants to see a photo.jpg how
this looks on a inner wing of my TR 6 just before the wing comes on give me an
email.
For other sheet metal gaps like floor panel to sill one can use a paintable
polyurethane sealing compound .

The last thing:
Why does M.L. keep her mouth firmly closed...???????
Rumours say she is hiding evidence !
