Like Steve’s, my experience with Lexel is that after much storage time it gums up in the tube’s nozzle and that chunk’s gotta get outa the way before more fluid, workable product is available. I use narrow metal probes to dig at the plug and squeeze until the usual 1 inch gets expressed. Then the less viscous, good portion squeezes out nicely, but it sets up relatively fast, so you’ve got to use a wet finger within minutes to level the bead or else it gets tacky and difficult. I keep a small dish of water or wet rag handy to rewet my finger repeatedly during any job over a foot long or that’s intricate and slow.
But as long as the surface was properly cleaned, and the stuff worked well into and over cracks or seams, Lexel is unsurpassed in preventing water intrusion. Word is it works in water also, which if it can be made to stick, would be a life saver on the roof or slideout in a rain storm.
