A couple of weeks back, I lubricated my roof seals with the GPL205 Krytox grease (thanks of course to the valuable information found on this site). The results are as follows:
Almost immediately, the grease, which at least a little of remains on the seal, catches road and environment "dust", including fine road sand. This did not make me happy, as a) it looked bad, and b) I felt it would not be good for the seal for sand and dirt to be squeezed between the glass and rubber. I have wiped and washed the seals a few times since then, which removes most, but not all, of this held dirt.
I have also had one "pinch" since then, with very few openings (crappy Spring so far here in NY).
I will say that the stuff is pretty amazing. I kinda get the feeling it will never wear off, since it has retained the exact same hydrophobic properties as the day I put it on.
Haven't had any leaks before or since (except in my trunk, but that's in another post).
Just curious if anyone else has had the dirt-trapping problem with the grease, and any idea how to remedy. Do you think I simply left too much on? I did try to spread it thin with my finger...
