900 Moldable Silicone Putty - Black

Funciona bien

I needed this to seal a couple of spots in my RV, where water was finding its way through the driver's door window seals. It's very easy to apply and to mould. After a few rain storms, the leaks were finally confirmed gone. Recommended stuff.

I had to remove a front metal panel to access my air conditioning evaporator on top of my heater. (The coils needed defrosting). All went well, but I had trouble replacing the panel. It would not go into its slot, and the screw holes would not line up. After careful analysis, I realized that I had to completely remove the old putty, reinstall the panel, and and then seal where the pipes came out with new putty. The old putty was still soft, but not very malleable. The E/FUSING 900 Moldable Silicone Putty was very easy to work with, and sealed perfectly. It saved me the cost of a service call. It is clean to work with -- not oily, not smudgy, non-staining, and just the right amount of malleability. I expect it to retain its shape and seal forever. In the photo, the black putty is the E900. The gray putty is the original putty from when the heater and A/C was installed. I WOULD LIKE TO SHARE A LESSON LEARNED: Change your heater-A/C filter frequently enough so that it does not become clogged. Otherwise you can end up with a block of ice around your evaporator coils, reduced flow of cold air, blocked and overflowing condensate drainage and insufficient air conditioning.

Happy with the performance so far. Sufficiently malleable, adhesion is good… but certainly time will tell with outdoor exposure.

Just what I needed to fix the slightly out-of-spec drain hole in my Kolher cast-iron sink. Man, this stuff is NICE. It's like a slightly stiffer Silly Putty, but you can tell it has Silicone in it. No stain, no mess, it just works.
