we put it on around 11pm last night, but winged several things.
for instance, we couldn't quite figure out what size the standoff spacers were supposed to be so they would keep the glass from hitting the metal, so we just put down extra urethane.
we also couldn't figure out what cutting the 'V' on the urethane tube meant initially so we just cut an oval. later my son, realized what the 'V' is all about. the way to do it would seem to be to cut the tube at 90 degrees to get a circle. then you cut out a 'V' as indicated on part of the tube just touching the circle. now when you squeeze the trigger, the bead comes out in a triangle-like shape. the reason for this shape seems to have to do with assisting the glass to settle down nicely. floor and wall tile trowels often have triangular or square 'teeth' which create little waves on the adhesive. the crests of these waves are structurally weak so when you push the tile down, they collapse forming a flat surface which is much harder to compress. similarly, the point of the 'V' is structurally weak, so as you push the glass down, it collapses to a point where there is a greater amount of urethane. to push down on this urethane would require a great deal of force - in fact, you'd have to squish it out beyond the edge of the glass. as such, it lets the glass settle on a fairly firm platform to cure.
we also put the urethane on the car not the glass as the tsm instructed because we saw a lot of people doing just that and because we didn't have suction cups, it was going to be difficult to grab the glass and install it without getting the stuff on your hands. it was also easier to get extra urethane into areas we thought might require it. needless to say we ended up putting too much urethane on, but then pushed some of it into place with a putty knife from the edge. the job looks quite clean and neat now.
we'll be letting it cure for more than 24 hrs before driving - it's not cold here, but hardly warm either.
we didn't use all the urethane in the tube, so we taped up the opening, but i rather doubt we'll be able to stop it from curing, unless there is an intelligent way to store urethane in a mostly empty tube?
in friendship,
