Rated 5 out of 5 by Great Product I needed sealant/adhesive to bond perspex to metal on a camper van conversion, this was perfect, water tight seal. 30 Nov 2015
Rated 5 out of 5 by Excellent sealer Great product , did exactly what I needed it to after another product had let me down !! Was a lot thicker than most silicone which was exactly what I needed !! 29 Apr 2015
Rated 4 out of 5 by Good roof sealant Good stuff for sealing those very annoying corners on roof windows where the manufactures flashing is not up to the job. Also good for sealing gutter joints when using different manufactures products that don't quite fit as they should. A bit pricy for what it is though. 18 Dec 2014
