Here are some tips for application: When you cut the tip, only cut the opening as wide as the bead size you need. Wear gloves and have a cleaning solvent and rag ready for cleanup. I found that even when properly resealing the cartridge, the sealant dries inside the tube and it's a pain to get it unclogged.
For performance this product gets five stars, but to be fair, I had to knock off one star because of the usability issues I mentioned. Although not a perfect five star score, this product is a necessity due to its ability to flex after drying. I highly recommend the product on any RV.
There is a learning curve, or there was for me. I am used to caulking and running my wet finger over it. If you need to do that with this caulk, you need to do it quickly. It skins pretty fast on a hot day in SC humidity. Also, if you tape, as I did for the first two areas, you need to remove the tape within a minute or so. Otherwise, it will lift the caulk with it.
If you cut the tip at an angle and run a nice, smooth steady bead, you can avoid tape and smoothing. I was able to do that on the last two areas of the caulking job. I re-caulked the two refrigerator vent areas, the a/c compartment, and the door handle. I used about half of a tube.
I removed everything before caulking. I cleaned the area with a razor blade and a rag with mineral spirits. A fine Scotch-Brite pad might have been easier than the rag. Be careful with the razor blade so that you don't gouge the gel coat. Then, I sprayed it with window cleaner and wiped it dry. I caulked a little behind the items (not so much that it oozes out) I removed and installed the items while the caulk was still wet. Then, I caulked around them.

This will be my go to for sealing my trailer edges from now on. I'm impressed with how strong it is.
This cannot be compared to regular silicone, it cures into a completely different critter.
