The vinyl material used in tops is produced with a plasticizer which is an=
additive that makes the vinyl soft, pliable and stretchable.=C2=A0 The pro=
blem is this product is volatile and will dissipate over time making the to=
p less and less stretchable.=C2=A0 If the top stretched whens installed (an=
d installers don't like wrinkles and the easiest way to remove wrinkles is =
the stretch the top to remove them) it will become more difficult to erect,=
especially when cold.=C2=A0 When I rebuilt my TR6 in 1996 a friend gave me=
a top that was sitting in his basement for 20-odd years (he bought it but =
his car was totaled before he could get it installed).=C2=A0 I had that top=
installed and it was a dream to erect and fold the whole time I had it.=C2=
=A0 I attribute that to the fact that it wasn't stretchable when installed.
My advice is to get your top installed when the weather is cold and the mat=
erial is more resistant to stretching.=C2=A0 The installer will pre-stretch=
the top less and it will work better in the long run.
Here's another anecdote: I bought a tonneau for the TR3 which was, in my op=
inion, cut about 1 inch too short.=C2=A0 I installed the Lift-A-Dot snaps a=
s close to the edges as I could but still could only install it on a hot da=
y in the sun.=C2=A0 Since this car lives mostly in the garage the tonneau i=
s virtually permanently installed and over the years as the cover gets less=
stretchy it has become easier to install.=C2=A0 I think the plasticizer ha=
s dissipated and the top took a set in the stretched position.=C2=A0 So, th=
is raises a question: What would happen if one slit some garden hose and pl=
aced it over the bows and left the top up with a little extra stretch.=C2=
=A0 After a while the top will take a set with extra slack, perhaps making =
it easier to put up.
Or buy your top years before you install it.
