### ⭐⭐⭐⭐⭐ Professional grade sealant.
*by R***E on April 1, 2026*

Before I retired, my company was excellent at ceiling water leaks. Sika was the best product in areas exposed to ultraviolet light. I recently used it when installing a new skylight on my RV. Knowing that it’s difficult to clean up, I blue taped all edges and had rags with solvent nearby. The job went very smoothly, I was impressed how easily it adhered and spread evenly. Cleanup turned out to be no problem for me.
