Best Sealnt for rooftop cable drilled hole.

[Margaux2]

What is the best Silkaflex product number please for an electric cable (awning led strip light) running through a gland on the roof of a motorhome? Or is there a better product?

You can use CT1 top product or cheaper puraflex 40; both available at your local toolstation for pick up.
CT1 is my favoured, used it in noumerous jobs including swiming pool under water. It’s excelent, and very stable with UV.
