Silicone and new technology?
Replaced my "gravity water fill" today. I fixed the usual way. Put some putty tape around the back and screwed back into place. Talking to parts guy as to what type of silicone to use just to c...

The Geocel polymer sealants are stiffer and have more density than the usual caulks, including silicone. This makes them a bit harder to tool after applying. One trick is to heat the tube before application. This will soften the material a small bit before application.
I use a lot of different caulks and sealants in my business and inevitably, a rookie worker will just make a mess of things when first using caulks and a gun. One trick is to cut the spout small, I only cut enough to insert the wire tool to puncture the tube. Or, if I need a large bead, to cut more spout but always to cut it smaller than the result I'm after. I tool nearly all beads as I believe I get better adhesion and it looks better. For a small length, I'll use a wet finger. If I do a whole house, I'll use a caulk tool or a spoon. To control speed or amount of sealant dispensed, you need a caulk gun with variable dispensing, not the cheap ones with a notched rod. After a few hundred tubes, you'll know exactly how much to pull the trigger.
Silicone is the Devil, don't use it on your RV. It makes an excellent sealant for mating surfaces held by compression like oil pans and valve covers.
