Perfect for RV Sink & Shower Repairs
We used this sealant on our RV’s kitchen sink and in the shower when we installed new faucet turners and a new shower head, and it worked perfectly. It’s easy to apply, flexible, and creates a solid, clean seal that feels really secure. So far everything has held up great with no leaks or issues. For RV repairs and small plumbing updates, this stuff really gets the job done. Definitely a reliable product to keep on hand.

Great new packaging.
Great product and wonderful tube upgrade. Plastic tube has a removable screw tip with a precut small opening. This worked great for the small gaps I resealed. Tip cleaned out easily with mineral spirits. I sealed the tube with three layers of plastic wrap and lightly replaced the tip. We will see if it stores well, but punching a cured plug out will be easy with the tip removed. Thank You for the improvements.

Good but more translucent than white
Seems to work fine. My only complaint is that it isn’t really white as advertised. In my application I was looking for a solid white. This is a translucent white.

Specific product for your high $ RV
Great product, that is very specific to an RV application. Do your research and get the best product for your application. This is not a silicone, and is compatible with most exterior RV fiberglass and hardware applications. Fast shipping too.

The Best Product On the Market
This is an excellent product. It performs as advertised. I could not have found a better product. Worth every penny. I very highly recommend this product and will be purchasing more. I had never caulked anything before. The company was able to tell me exactly what to do and how long it could take to fully cure. I chose the clear so my amature efforts wouldn't show without a closer look. It was much easier than I thought it would be. I did learn that because of the Florida humidity it could take 10 days to fully cure. It took, roughly, 18 hours to cure enough not to be tacky. For those living in dryer climates it will take less time. Since this is a flexible caulk it will feel rubbery to the touch even when fully cured. While some may complain it takes too long to fully cure, remember that as soon as it has cured enough to no longer be tacky it is sealing out water. To those who complain it takes too long to cure in high humidity environments, be impatient as impatience is how simple jobs very often become major undertakings.

Great product - This is the one you want.
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.

Maintenance is key
I buy this for my RV. Shipping is always fast and it's always packaged well. I am a repeat customer and have had no problems with the product at all. I will also add that I don't run into any of the issues that some people have posted about. It goes on very simply and takes a few days to cure. It seals the seams as intended. Just like with any equipment maintenance is key.

Non silicone - Top notch for the RV rig. Pricey but performance is well above other similar products.

Purchased to re-caulk the sides of our travel trailer at the seams. Found it works really well and I would recommend to anyone using it for the same purpose. I am hoping it stands the test of time. Our trailer is a 2018, and it looked like Jayco used some type of putty along the side seams. I removed all of that putty and used this flexible sealant to replace it. It went on very easily and it feels like it will work fine. I used it at the end of last season, so we will see how it holds up over summer use when exposed to the elements.
