Good point about the glass cleaner Bartomos. I do know that ammonia and urethane adhesives don't mix per the mfgs. The only time I've put tape on the body was with a light colored paint job that we weren't sure if the sealer would stain the paint because it hadn't fully cured (not the most comfortable position to be put in). I don't know what the sealers were that were used in the 50's, but they seem to be different than what we had in the 70's, just like todays are slightly different. Also, when you are doing something everyday you like to stick with the same product as much as possible because you know the working characteristics. John
