One of the best user-friendly adhesives available. Used this for 40 years, on masonry, wood, metal(with prep) and some plastic (with prep).It's two-part, thick, stringy hence messy, but well worth the care in application (and cleanup ... with acetone).Surfaces must be free of oil, dirt, grease. For slick surfaces hand roughing with 250 grit advised.Reasonably water-proof outdoors. Don't know about immersed stability.PC-7 equally good, but not rated for marine use.
