Gloop in a tube.
I think this is as good as CT1 for less money. Time will tell. Used for sealing around a window and glueing some rubber roof. Great for cracks and flaps.

Great quality and great colour
Great quality, perfect dark brown colour. We have dark wood panels on the kitchen ceiling with spotlights. There was a tiny gap between the two of panels which the light was coming through that gap and didn’t look nice so I wanted to fill that gap. This brown sealant was perfect , exact brown colour i was looking for ,went on so smoothly and has no smell. Very happy with my purchase.

Best on the market
The best sealant / adhesive on the market, love it. It will seal of fix most things
P**.
Very strong but stays just slightly pliable where a little flexibility is appreciated.
High quality product. Professional grade. Strong adhesion properties but can be removed if needed. I used it in the automotive area to bond a metal bracket to glass.
