The best for the bathtub. I have had it for five years and it feels like I installed it yesterday. I have a hotel with many bathtubs and none have had any problems. Apply the silicone and then use the special spatulas to remove the excess. I tried both Patex and Würth but they are not even close. It is the best. Don't look for anything else. Just buy it and you're done.

As a glue, it is good. As durability, it is good. As application, it is good. But unfortunately, the negative aspect is that I have used it in the bathroom and it turned white and yellow, just like the transparent one in an outdoor area. Considering the relatively economical and better options, I would prefer the Pattex SP101. Furthermore, the warranty is from Sika, the 11FC, but you have to finish it quickly because it is polyurethane and if you leave it for a long time, it dries out and you have to throw it away.
