<div> <font size="3">The vinyl material used in tops is produced with a plasticizer which is an additive that makes the vinyl soft, pliable and stretchable. The problem is this product is volatile and will dissipate over time making the top less and less stretchable. If the top </font><font size="3"><font size="3">stretched when</font>s installed (and 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. 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). I had that top installed and it was a dream to erect and fold the whole time I had it. I attribute that to the fact that it wasn't stretchable when installed.</font></div>

<div><font size="3">My advice is to get your top installed when the weather is cold and the material is more resistant to stretching. The installer will pre-stretch the top less and it will work better in the long run.</font></div>

<div><font size="3">Here's another anecdote: I bought a tonneau for the TR3 which was, in my opinion, cut about 1 inch too short. I installed the Lift-A-Dot snaps as close to the edges as I could but still could only install it on a hot day in the sun. Since this car lives mostly in the garage the tonneau is virtually permanently installed and over the years as the cover gets less stretchy it has become easier to install. I think the plasticizer has dissipated and the top took a set in the stretched position. So, this raises a question: What would happen if one slit some garden hose and placed it over the bows and left the top up with a little extra stretch. After a while the top will take a set with extra slack, perhaps making it easier to put up.</font></div>

<div class="yiv8638386929MsoPlainText">I, too, have had problems with the Robbins tops although my car is a TR3A, not a TR6.</div>
<div class="yiv8638386929MsoPlainText"> </div>
<div class="yiv8638386929MsoPlainText">Like Bob with his TR6, my tonneau (and also a convertible top) is so tight that I can only fit it with great effort even in warm sunny weather. The tonneau was installed by professional installers who complained about the fit. Robbins was responsive when I complained. I even sent my previous tonneau to them so they could see what fit, but the replacement they sent me after that was no better.</div>
<div class="yiv8638386929MsoPlainText"> </div>
<div class="yiv8638386929MsoPlainText">The top hasn’t stretched or loosened over time. If anything, it may have shrunk because it seems as hard or harder than ever to put on.</div>
<div class="yiv8638386929MsoPlainText"> </div>
<div class="yiv8638386929MsoPlainText">I would suggest having the top (tonneau or convertible) made by your installer so that you get a good fit. That would have been cheaper for me than buying the Robbins tonneau and having to pay for two installations.</div>
<div class="yiv8638386929MsoPlainText"> </div>
<div class="yiv8638386929MsoPlainText">As always, particularly since you’re dealing with a TR6 not a TR3A, YMMV</div>
