I know this topic has come up before but I used this stuff recently and it works very well. I bought 1 can. I sprayed four lnb lens, and applied a light coat to a 76cm channel master, a 85 cm Patriot and a dish 500. That was really streching it but I only had the one can. I did not know how well it would work. This last week we had a good amount of rain followed by some freezing rain and then snow. I did lose a few points on the meter but never lost a signal/ channel. I usually lost or had breakups on 11720 on G10R with any amount of rain. This stuff works great, I only wish I would have bought two cans at the time so I could have put the recomended amount on the dishes. I'll pick up another can the next time I order something. I got it form Sadoun's website btw.
