Best i have found
I had water issues in my garage for years. This product cured my problem. I went back and purchased more for a different project because it worked so well. I have tried other products, this one is the best by far.

A little time and a tube of adhesive calk saved me $2000
The product worked perfectly, it was easy to use, thick enough to fill the holes as well as gaps and added great adhesion to the rubberized tape I used. Unfortunately during an ice storm this winter a tree broke off and a twenty foot section fell on our camper. This resulted in the AC cover, and the Refrigerator roof vent being broken along with several tears and a few larger holes in the rubberized roof material. This adhesive calk worked perfectly to seal everything up including a leak around the TV antenna I have been trying to fix for a while now. We have had two days of continuous rain and not one drop of water penetrated the roof. I was expecting to have to replace the whole roof ($2000) this product worked to seal everything. I did put a rubberized tape over the adhesive calk to add a layer of extra protection. The next nice day I have free I am going to try the roof cleaner, I will post an update.

Great product
Great seal and flexibility. Good adhesion. Nice to be able to just order and not have to go to the box store. Applies thick as needed. Value compared to store is equal. Wipes off like any other chalk or sealant.

Not great
Water peels it up after a while

Great caulk
I'm working on my deck and this caulk is great for fixing cracks. It's thicker than most caulk so get ready for hand cramps after you use it

Solid as a rock, but flexible and fierce
WOW. What an awesome product. I used this to fill some gaps in my epdm pond liner (put seam tape over it after it cured, then coated with primer/neopond). The job was intimidating until Liquid Rubber came to the rescue. This stuff is a great adhesive AND waterproof rubber filler. What was once an anxious mess of an issue is now a breeze because of the liquid rubber suite of products. This caulk holds its shape, it sets up SO fast, and you can paint it in 24 hours. I mean WOW. I never thought I could be so excited about a waterproofing product, but I love this and Liquid Rubber earned a customer for life.

Blanc
La couleur est réellement un beau blanc, il est vrai que ce produit est réellement bien adhésif même pour l'extérieur la durabilité reste à voir. Un paquet de cartes est très bien puisqu'il n'est pas beaucoup liquide il s'étend moins bien mais c'est ce qui fait sa bonne adhérence je crois.

Better than silicone
Excellent product. I used it to replace silicone caulking on a door sill which had started to leak after only six months. This clear caulking applies easily (I cleaned the area with rubbing alcohol first) and applied. Product is holding up just great against the elements. Yes, it is more expensive but well worth the additional money. Would be nice if it came in additional colours.
