Review: Great for Camper Caulking - I have a vintage Avion camper and bought this to caulk the seals and windows. My camper is anodized aluminum so I had to purchase the right sealant. Was not advised to use silicone caulk so I stumbled upon this Sikaflex sealant. I purchased smaller syringes to fill up and piped the sealant on the seams and around the windows with ease. Still have more sealing to do but very satisfied with this product.
Review: This stuff is a miracle - Sikaflex 221 is a miracle product. If you want something glued down and sealed off simultaneously, and you want that thing to never move again, this is the stuff. If there is any chance that you may have to remove that thing some day, think twice! To say this stuff is hard to remove is a huge understatement. It is virtually impossible to cut with a knife, and the bond it forms with whatever you put it on is absolute. You are very likely to destroy things in the process of trying to remove Sikaflex 221. I have used this stuff to mount solar panels to vehicle roofs. Once cured, it's just as solid as if I had used screws. I have no doubt at all about its strength, and it is water tight. Years later, and I am not seeing any cracking or aging of the material. It's amazing.

## Questions & Answers

**Q: Will this adhere well to wood?**
A: This stuff sticks to anything better than any product I've ever used. It will stick to wood really well.

**Q: Would this work to attach flexible solar panels to the roof of a cargo van?**
A: Contrary to the other answers, the Sikaflex manufacturer's website indicates that it is also a high strength adhesive: 
Sikaflex®-221 is a high-quality multi-purpose non-sag 1-c polyurethane sealant/adhesive.  Sikaflex®-221 bonds well to a wide variety of substrates and is suitable for making permanent elastic seals of high adhesive strength. Suitable substrate materials are wood, metals, metal primers and paint coatings (2-c systems), ceramic materials and plastics.

**Q: would this be great stuff to seal an aluminum enclosed trailer roof?**
A: I am on a horse trailer forum and this was recommended by several people with 60+ years in trailer repair. They swear by it.

**Q: Can 221 be used for Aluminum Boat repair below water line?**
A: Not positive but think it can not be used like that

a great caulk for RV's! easy to work with, and clean up. Drys fast and remains semi rubbery for good seal.
