So what’s the best shower caulk for RV shower?
Here’s my top 3 picks:
- Geocel 28100V Pro Flex Crystal Clear RV Flexible Sealant
- Gorilla 806002 100% Silicone Sealant
- Flex Shot Rubber Adhesive Sealant Caulk
If I had to pick just 1 it would be the Geocel 28100V Pro Flex Crystal Clear RV Flexible Sealant because of its durability. It is also sealable, paintable, high-quality, resistant to dirt pick-up and can handle any temperature.
However, I would avoid the BioSeal Translucent Silicone Caulk because of its low consumer reviews.
