It is amazing what this stuff can do

5/5

If you are looking for a product that can bond and seal at the same time, and you want that thing never to move again, you need to use Sikaflex 221. It is very hard to get this stuff off! If you think there is any chance you may need to remove it sometime in the future, think twice. With the knife, you cannot cut through it, and no matter where you apply it, it forms a bond not easily broken. Sikaflex 221 is a very dangerous product and you will likely destroy things in the process of removing it. Previously I used this stuff to mount solar panels on top of vehicles. Curing the jars makes them as solid as if they had been fixed with Despite the fact that it is water-tight, I have no doubt what its strength is. It's been years since the material cracked or ages, so I have yet to see any deterioration. What an amazing experience.

You've got great stuff there

3/5

When this isn't damaged or expired, I'm sure this stuff works great. Do you really think Amazon is that big? My friends and family may need to be warned in the RV forums if this problem isn't resolved soon. This is absurd.
