Review: Best caulk I have found for shower surrounds - Stays clear and does not yellow. Like everything else, when used in a shower surround maintenance cleaning helps keep it looking great. I did not have this product when I did my other shower, and the top of the line big box 10 year no yellow/mold bathroom caulk claim is bogus, didn't last 2. The good part was that the big box caulk came off easily and took no time to replace. I have had this caulk in another bathroom for 4 years and it is as clear as ever, with zero mold. Tooling was a bit harder with this tube than I remembered, but this caulk has really great adhesion, but it looks really good for much longer than any other caulk I have used. I used to have to go to the local glass installers to purchase, and for a premium price, but found it on desertcart. This is really good caulk, but with any caulk you may need to use a primer on certain surfaces. For fiberglass surround and polished nickle aluminum it worked just fine without the primer. Just be careful not to feather out too thin on the edges (just like all caulks) and you will be very happy.
Review: Great quality - This CRL is what the local RV place uses.. Works awesome

## Questions & Answers

**Q: Will this work as an adhesive/silicone for installing undermount sinks to a marble vanity top?**
A: It is the adhesive that the granite counter top installer recommended I use to reattach the stainless steel under mount sink that was installed about ten years ago and that had become detached on the garbage disposal side of the sink.  I did not have to remove the whole sink but rather scrapped out the old adhesive and squeezed new in the space. I was instructed to brace the sink in place and allow the adhesive to dry for several days which I did.  The sink is holding fine.

**Q: Can i use this  for exterior application? seal window?**
A: That's what I use it for.  I seal all external seams and around windows, etc.  I also seal over butyl caulked seams. This sealant should NOT be used around vents or devices on EPDM and TPO trailer roofs.

**Q: Will this work for sealing the inside corners of a shower on top of the grout?**
A: Yes 100%

**Q: Do I need a caulking gun or I can easily just squeeze the content out to seal ?**
A: Hi,  

You will need a caulking gun if your seal will be seen (as in a bathroom application) in order to control a consistent flow or bead along the edge that you are sealing.
