Review on XFasten 8 Inch 30 Foot Sealing Patching RV Parts & Accessories by Jorge Kehayas

This stuff is sticky enough to be a nuisance and not pliable enough to be effective - worst of both worlds. If you are replacing window glass and it is a new house where everything is brand new then this would be a good material for glass but if your house is a bit older and the surface may not be perfectly flat then this material is not suitable. not malleable enough to make a clean print -- - it's hard to explain, but buy it and you'll see what I mean.
