They have chosen Dekal sealant for sealing roofs, skylights, side-mounted hatches and moldings, windows, and underbody penetrations.
It was good to receive a quality product suitable for fixing the window when ordering the window. Easy to use product.
No experience yet (installation work not yet done)
Standard butyl, i.e. very difficult to use (messy)
Very easy to use and functional for the applications I ordered the product for.
