GeocelGC28100 Pro Flex RV Flexible Sealant - Clear

Good quality

Used this product to caulk the seams of a camper. First time doing this or any caulking at all except for caulking an old window once. I'm a girl who does not look forward to this type of work, but this product was fairly easy to apply and seems to have done a good job. I like the fact that this product is clear and that you can apply it over itself if repairs need done later, rather than having to remove all the old caulk. Looks neat too, which is very important to me.

This is the product you want if you want an RV caulk that dries without being tacky and stays flexible. It is similar to the original caulk that is on our Aliner. It dries almost like silicone but is a little more solid.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.

Overall a very good sealant for an RV. I purchased this product due to it being a flexible sealant that will endure the flexing of an RV as it travels down the highway. This sealant is more difficult to apply than regular silicone products.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.

SUPER tacky and don’t run. Was easy to use and is nice and clear so it isn’t an eye sore.

This stuff is tough. Will definitely stick to anything. Very clear and easy to work with as soon as you put it on. Don’t wait to smooth out because it starts setting . Have some alcohol or WD 40 ready to clean your finger before the next application. Don’t cut the end of the tube too big. This way you can install a red wire nut to the end of the tube and use again later.

Great product works very well would highly recommend.

Used to seal a cargo trailer conversion. Appears to have worked. It can be messy like most caulk. Make sure to cut the tip very small.
