I am ready to sika my windscreen on, only 1.5 years after using sika on the sliding canopy. The cleaner and primer have rather short shelf lives and mine has long since expired. I'm wondering if anyone has some leftover and would be willing to send it to me. Its really unfortunate that one can't buy that stuff in smaller quantities as I had 3/4's of the bottle leftover of each after doing the slider. I don't need much, just enough for the rollbar. Willing to pay.
