The rationale for "dry" glue is like this: layer on the base tape, layer on the rim, SOME people treat those as sticky-to-each-other sorta like rubber cement. But I do this: when I want to mount a tire, I apply a third thin layer to the center of the rim, and stretch the ("pre-stretched") tire into place on the rim. The wet glue makes it a LOT easier to do any centering of the tire onto the rim, then the solvent in the mastic infiltrates the two outer dried layers and with the glue in the middle after drying is a very secure, clean, non-roll-able bond. All this without tissue cloth on the sidewalls/rims a'la Ted Ernst (which wouldn't work anyway on road bikes with rim brakes and such.) Its like a sandwich made with no butter, if you spread jelly on it and slap the slices of bread together, the jelly soaks some into both slices. Let it sit for a while. The bread's STUCK together -smile-
