Update from 10/24/2020 (~4.5 months):
The X5 has continued to live outside 80% of time, including during inclement weather.
There hasn’t been much good rain lately and I haven’t had time to take decent roof pictures, but I snapped these this morning after steady rain all Friday night.
NOTE: Only the Coating Lite Wannabes on the middle-back roof and WG CSC on front passenger side are remaining in this test. The rest were dead/dying and removed in the last update. I again forgot to take pictures of WG CSC, but it’s still doing well, but hard to compare with the other 4 since it’s off on it’s own. My guess is that it’s doing as well as the top 2.
Middle-Back Roof:
I know it’s not easy to take or see detail in roof pictures. But based on beading, I rank the following:
Coating lite wannabes:
1) Feynlab
2) Wowo’s CS
3) IGL
4) TW Hybrid Solutions CSC
Feynlab looks as good as Wowo’s, and I give it the win because it’s in the middle where water pools the most and beading generally looks the worst... and it fully sheets a few seconds faster after a wash.
IGL which started off as the most impressive of these 4 is a notch below at 4.5 months, but certainly still alive. Beading is getting less uniform and larger.
TW HS CSC is still hanging on somehow. As noted in the previous update, some days it looks almost dead, but then it seems to come back to life after a wash with Reset. It sheeted the slowest after the last wash.
I’ll try to get some sheeting pictures next wash if my wife can help with pics. It’s too hard to take useful overhead pics on my own. I also need to remember the front roof WG is still in play and get some pics.
