I have always loved the castrol stuff for the winshields. The someone convinced me to try Rain-X again. I stopped using it because of glare it would cause at night. Well I tried Rain-X again and again I still hated it. Compared to the Castrol stuff it seemed to leave a fine haze on the windows that caused a glare when driving at night.
The Castrol stuff is hard to find now, I was only able to find it at a Walmart recently after hitting 4 other autoparts stores. I cleaned and reapplied with Castrol and the winshield beads like mad and no glare.
