Great product. Sticks to anything hard as a rock. Use it on RVs travel trailers vehicles. I even used it on a house with stress cracks. Works great.

Good product however Color is somewhat opaque.
I used it to patch small holes caused by corrosion on my RV aluminum siding. I bought white color to match the RV, however the sealant does not have a lot of white pigment which made it somewhat opaque (can see the hole/discoloration through it. Other than that issue it is a really good product. It smoothed out nicely and seems to have made a good seal to keep out moisture.

Good stuff but be aware of what you're working with
I used this to seal the wiper seal on my camper. This is not caulk or silicon so when you run a bead and want to shape it with your finger or tool, do so quickly. It skin's fast.

This stuff works perfect on my RV roof
This stuff works perfect. If you have an RV, you should always keep a tube of it.

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.
