EternaBond tape is what most RV techs reach for when a seam splits, and the kit puts the three needed pieces together: a roll of RoofSeal MicroSealant tape 4 inches wide by 50 feet long at 35 mil thick, a can of EternaClean spray and a can of EternaPrime surface conditioner. Some versions of the kit add a tube of caulk and a steel roller. Bundles run near 110 dollars, which feels steep for tape until you price a rotted roof deck.
The tape bonds on contact and will not reposition, so measure, wipe, prime the dusty areas and lay it in one pass with heavy roller pressure. Taking it off later means a heat gun and patience. Right for seams, vent flanges, skylights and tears. Wrong as a way to cover an entire chalky roof.
