Review: 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.
