Review: OB1 Black Multi-Surface Construction Sealant & Adhesive - I used the "OB1 Black Multi-Surface Construction Sealant & Adhesive" to stick down corner trims and seal the edges of my van lining that I did. The silicon had good adhesion for the trims I was sticking down and it was very workable. It does not set too quick and did not skin over at all so I was able to get a nice finish to it without ridges or the "dragging effect" you sometimes get when silicons start to skin over. This silicon was also pretty odourless. My tube came with a nozzle also.
Review: Excellent stuff - Excellent product and great value for money easy to Use and dries quickly will definitely buy more
